Hi, thank you for your message! The issue seems to be in the package name, case of some letters. The old version uses folder "com.playito.songbeater" while the newer one "com.Playito.SongBeater" (and we will keep this new name). So please copy your CustomSongs folder from the old one to the new one. And we will also contact SideQuest support to update shortcut for Song Beater to this new location. Sorry for the inconvenience!

Have you started the game at least once after reinstalling? It saves the profile with data at that moment. Then the path "\sdcard\Android\data\com.Playito.SongBeater\CustomSongs" should be available as seen here in sidequest file explorer: https://imgur.com/a/JJDWSiI
