Musicolet Music Player vs Lisna Music Folder Tree Player

You can optionally support the developer and pay for pro features, but the free version isn't missing any core features.

Intuitive options to decide what to do when song or "queue" ends.

Supports many audio formats natively, as well as all formats supported by the system decoder of the Android device in use.

The app doesn't include the Internet permission, so no user data can be sent to the app author.
