Retro Music uses the native media player that comes with your Android phone, so as long as a file type is supported by your phone, it's supported by Retro Music.
Try checking up if those songs are not less than 30 seconds, if so head to settings -> other -> filter song duration. Put this to zero and see the songs should start appearimg in the library.
If this doesn't work out for you, re-scanning the media folder should help and subsquently rebooting the device to refresh media store.
Playlist/Playlist songs disappearing is based on android media store system. Save those playlist as file(Tap on three dot menu next to available playlist and save as file) and it should get fixed.
If you are seeing duplication of songs in the library or no songs at all, then it's because of Media Store issue which got affected by some other app.
To fix this:
• Head to your device settings
• Open up "Apps & notifications" (This name depends from ROM to ROM)
• Find 'Media storage' app and clear storage (both data and cache) of it.
• Then open Retro Music app and manually scan your music from your storage.
• Reboot the device to refresh media store (Not sure if this is necessary)
NOTE: Don't panic when you will open Retro Music and see "Zero" songs there in the library. It's because you cleared Media Store which is responsible for recognising files on your device.
