Anybody using a particular mp3 player app on their android phone that they'd recommend? I've got some credit I want to use but there are a million out there.

I use Mediamonkey. If you don't care about auto-playlists (like itunes smart playlists) it's free.

I like Pulsar+, BlackPlayer EX, and VLC player best.

I've been using Shuttle+ for years. Not saying there aren't better ones, but it was one of the first I tried that I liked enough and found easy to use, and just kept using it. I don't use playlists. I just pick the artist I want, then the album, and play it.

After looking into this issue for many many years I have decided they all pretty much suck.
