Samsung Galaxy s6 Music Player Track Sort
Have been searching for a solution to this for a few days and have finally found one.


Open music
Top left drop down menu, go to tracks


If you only want to have it in alphabetical order in the app, stop here, if you want to fix the widget as well continue.


Go to more in the top right, edit
Top left, select all
Press more again, add to playlist
Create a playlist
Play a song in the playlist and go back to the home screen widget


This should fix the order :D
