Google Play Music app sucks

Most of my MP3s are not music, but sound files such as YouTube discussions. Obviously these don't come with their own album/song art, nor does the app know what to call it. That's ok, I'm willing to go in and set all of that up, but Google Play is clunky and inhospitable to editing art and titles.

Any suggestions on apps you've personally used which accommodate editing are appreciated :2wave:

I'm currently trying out Poweramp and I see an immediate improvement over Google Play as Poweramp imports art from the YouTube author eventhough it's a ripped MP3 of the video.

Edit:
Poweramp decided to import all my phone contacts and ringtones as albums. That's a bit retarded :lol:

I didn't reply to your post a couple of days ago when I saw it because I don't use programs to keep track of my music. I didn't have any suggestions to make. But I came across this program in a tech site I read and thought it might be worth your attention.
