Flipper/Music_Player/RTTTL_TXT/ReadMe.md

If you've flashed firmware that doesn't seem to include the Music Player (but see it as an option), try creating a "music_player" folder on the SD (ext) and pop some tunes in! You can use RTTTL (in TXT format) or FMF (Flipper Music Format) files.

NOTE: Make sure to put the TXT And FMF files in the root of the music_player folder for them to work!

Otherwise, you can access them through the file browser on later firmwares.
