After upgrade to Android 5, why won't most of my music files play?

[AC Question]

After upgrade to Android 5 most of my music files won't play.

After upgrade to Android 5 most of my music files won't play. It only plays the mp3 files not the aac files. I have found players that say they play aac files but none work
