There is an Android version of VLC aka Video Lan Player
It's free, it will play mp3 and a variety of video formats
The original is a PC program that plays, streams, records, and had easy to create play lists
Android also has MX player for multi media
I like to check non Google Android download sites for older versions of programs before almost everything became advertising supported,
Just run a virus scan on each and every download before installing, and make sure everything on your Android device is backed up before installing a any new app
