User reviews

Useless

The app used to work fine now it just jumbles folders and songs together in a nonsensical way when trying to access files by artist. It doesn't appear to be able to handle ID tags properly.

Stopped playing my files

Worked fine, now won’t play linked files. Click the file in the file location and it plays just fine.

Unnecessary paywall

Making playlists offline locked behind paywall, which makes no sense at all considering that I already have the songs downloaded.

Doesn’t play next song

Doesn’t automatically play next song
