GoneMAD Music Player (Trial) vs Musicolet Music Player

GoneMAD features a built in tag editor that has mass tag editing support.

There are 2x1, 2x2, 4x1, 4x2, and 4x4 widgets.

Rather than scanning for music automatically (and possibly including ringtones, alarms, etc. in your music library), the user can choose which file folders GoneMad Music Player checks for music and exclude folders with audio files that the user doesn't want in their library.

GoneMAD features support for aac(mp4/m4a/m4b), mp3, ogg, flac, opus, tta, ape, wv, mpc, alac, wav, wma, adts(4.0+), and 3gp(4.0+).

From call handling to headset preferences there are so many options built into GoneMad that there is something for everybody.

GMMP's folder browser can replace filenames with the artist name and the name of the song, shuffle within a folder, repeat within a folder. It also allows you to add the entire contents of a folder to a playlist with only a few taps.

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.

You can multi-select songs to add to a playlist, and you can use your finger to drag one or multiple songs to the desired position in the playlist, for example. There is also a command to insert a selection of songs into the current playlist after the current song.

Also allows saving unlimited playlists for later use, and playlists can be exported as external .m3u files.
