Owning a modern smartphone like the Xiaomi Redmi 9 offers access to a wealth of multimedia capabilities, and music is not the last place to go. Many users, when switching from button phones or other brands, face the first difficulties in trying to transfer favorite tracks to a new device, a process that is not complicated, but requires an understanding of the Android file system and the features of the MIUI shell.
There are several proven methods to quickly and without loss of quality fill the library of your gadget, you can use a classic wired connection, wireless data protocols or cloud services, the choice of the particular method depends on how much data you need to move and what tools are at hand at the moment.
In this article, we will discuss each of the available options in detail, paying special attention to the typical errors that often occur in beginners. Proper file organization will help the full-time player automatically sort songs by artist and album, creating a comfortable environment for listening.
File preparation and format verification
Before you start transferring data directly, you need to make sure that your audio files are compatible with the smartphone software. Xiaomi Redmi 9, like most Android devices, natively supports popular compression formats such as MP3, AAC and WMA. If your music is stored in less common formats such as FLAC or WAV, the built-in player will also play them without problems, however, old or specific codecs may require the installation of a third-party application.
Organizing a music library on a computer will make it much easier to do this, and it's recommended that you pre-sort tracks by folder, by album title, or by artist name, so you can avoid the chaos of the playlist after copying, where hundreds of songs are mixed into one unstructured pile.
Pay attention to the bitrate of audio recordings. For listening through regular headphones or built-in speakers, 128-192 kbps is enough to provide a good balance between file size and sound. Audiophiles using external DACs or high-quality acoustics may prefer lossless formats, but it is worth considering that they take up significantly more space in the internal memory of the device.
⚠️ Note: Some files downloaded from unverified sources may contain malicious code or be corrupted. Before transferring to a smartphone, it is advisable to check them with antivirus on your computer.
Classical method: Connecting through USB-cable
The fastest and most reliable way to transfer a large amount of music is to use it. USB-This method does not require an Internet connection and provides maximum data transfer speed, which is critical if you plan to download several gigabytes of audio. To start, connect your smartphone to your computer, unlock the device screen and lower the notification curtain.
In the notification menu that appears, find the item that shows the current USB mode, usually signed as “Charge Only.” Click on it and select File Transfer (or MTP) mode. After that, the Xiaomi Redmi 9 operating system will display as an external drive or removable disk that can be read and written.
Open the folder on your computer, go to the root directory or internal memory. Find a folder called Music. If you don't have one, you can create it yourself by just right-clicking and selecting the appropriate item. Drag the previously prepared files or entire folders with albums into this directory.
☑️ Connection checklist by USB
Once you have finished copying, safely disable your device via Windows or macOS system tray to avoid damaging the file system. MIUI regular music player will automatically index new files and they will appear in the track list. If that hasn't happened, try restarting your smartphone or clearing the Music app's cache.
Wireless transmission via Mi Drop and Bluetooth
If you don't have a cable or your computer is in another room, you can use wireless technology. The Xiaomi ecosystem has a proprietary Mi Drop app (known as ShareMe in some regions), which allows you to transfer files at high speed over Wi-Fi Direct. This method is especially convenient for sharing music from other Android smartphones or computers on the same network.
To transfer from your computer, make sure both devices are connected to the same Wi-Fi network. Run Mi Drop on your phone, select Get Mode, and scan. QR-code or go to the specified IP-The web version interface allows you to simply push files into the browser window, and they instantly appear in the phone's memory.
A more versatile but slow way is Bluetooth.It's suitable for transferring multiple tracks on the fly, but is inefficient for downloading entire albums because of the slow speed. Turn on Bluetooth on both devices, pair and send files. Redmi 9 will have a file acceptance request that needs to be confirmed.
Why is Mi Drop faster than Bluetooth?
After downloading, you will need to manually move them to the desired directory through the built-in conductor so that the player sees them.
Use of cloud storage and streaming services
The modern approach to music involves not storing files directly on the device in favor of cloud technologies, services like Google Drive, Yandex.Disk or Dropbox allow you to upload a music collection to the Internet and download tracks to the Xiaomi Redmi 9 only as needed, saving precious space of internal memory.
Install a cloud storage app from Google Play, log in and upload your music archives from your computer. On your smartphone, you can open files directly from the cloud or set up offline access for select playlists. Many streaming platforms, such as Yandex.Music or Spotify, also allow you to download tracks for listening without the Internet if you have a subscription.
This method has its advantages: your collection syncs across devices, and losing your phone won’t result in loss of your music archive, but initially uploading the library to the cloud will still require a stable and fast Internet connection, preferably via Wi-Fi, so as not to waste mobile traffic.
| Method of transmission | Speed. | We need the Internet. | Convenience |
|---|---|---|---|
| USB Cable | Tall. | No. | Medium (need cable) |
| Mi Drop (Wi-Fi) | Very high. | No (locally) | High. |
| Bluetooth | Low. | No. | Low (long) |
| Cloud. | Depends on the network. | Yes. | Maximum. |
Work with the file system and conductor
For Advanced Music Management on Redmi 9 It's good to know the structure of the directories. The File Manager app, built-in, allows you not only to move files, but also to edit their metadata. Open the app, go to the Music category, or manually find a path. /internal_storage/Music/.
You can rename tracks, delete duplicates, or create subfolders for different genres. If you copy songs that are displayed with the wrong titles (for example, instead of the artist's name, you see the track number), the problem is that you can use the name of the artist. ID3-Special tag-editing apps allow you to correct this information by prescribing the correct album titles, years of release and covers.
You can also change the way you save downloadable music from messengers or browsers through the Explorer, specify the Music folder as the target in the bootloader settings, so that all downloaded files automatically fall into the library, which will eliminate the need for manual sorting in the future.
💡
Use the Hide Files feature in Explorer if you want to remove system or excess audio files from the view of a standard player without deleting them.
Solution: The phone can't see music
Often, users are faced with a situation where files are successfully copied, but they do not appear in the player. The first reason may be the presence of a hidden file in the music folder.nomedia. This system file tells the Android operating system to ignore the media content in this directory. Deleting this file (through the conductor with the display of hidden elements) usually solves the problem.
The second common cause is a media library indexing failure. The system simply “didn’t have time” to scan new files. In this case, it helps to reboot the device or clear the cache of the Music app through the Settings menu → Apps → All Apps → Music → Memory → Clear the cache.
If files are corrupted or unsupported, the player can also ignore them. Try opening a problematic track through a third-party player, such as VLC Player, which reads almost any format. If it can't see the file, then the audio file is broken and requires re-uploading or conversion.
⚠️ Note: Do not store music in Android system folders (such as root or System folder) this can lead to system errors or accidental deletion of files when updating your firmware.
💡
Most music display problems are solved by checking for the presence of the.nomedia file or simply restarting your smartphone to update your media base.
Optimization of reproduction and equalizer
Once the music is loaded, you should adjust the sound quality. Xiaomi Redmi 9 has a graphical equalizer built in, available in the audio settings or directly in the player interface. You can choose presets (Rock, Pop, Jazz) or create your profile by adjusting the frequencies manually for better compatibility with your headphones.
For surround sound enthusiasts, Mi Sound (or Xiaomi effect) is available. It programmatically expands the stereo and adds depth to the sound, which is especially noticeable when using wired headphones through a 3.5 mm connector. You can activate this option in the Settings menu → Sound and Vibration → Effects of Mi Sound.
Don't forget the Smart Speaker feature, which adapts the sound scene to the position of the phone (horizontally or vertically). Although this is more about video, some algorithms also affect the playback of music through external acoustics, making the sound more directional or diffuse.
