Music Stand furniture now keeps track of how many times a song has been copied.
Changed music stands so they no longer clear the copied tracker if you remove and add the same song back on(determined by notes, so useful if you change the tempo and/or titles or some such).
Increased the maximum tempo to 240bpm. Metronome may not be as accurate at this speed, but useful for playback.
You can now find a "Clear Old Files" at the bottom of your options that will delete all customs from your storage so you can hopefully clear out most of the filler data without needing to reinstall the game. It may take some time to delete all the files if you have a lot, depending on your device.
