Symfonium is great, and in its current state, probably the best Subsonic client for android. (Tempus is good enough for me though.) But best of luck if you ever have a nontrivial issue and ask the dev for help. That's one abrasive mf. (Just take a look here. It's hard to find anyone so full of themselves.)

That said, if it works for your needs, it's a great app. I won't judge anyone for using it, but I'm someone who can't and won't separate the art from its artist. If that applies to you, you've been warned.
