Black Stone Cherry - good hard metal/rock, if a bit over produced, but I picked up three of their albums after hearing a bit on Qriocity.

On that note, I'm listening to a bunch of stuff on Qriocity. After the free premium month I renewed it at the cheap level for another month to see if I'd actually use it if I had to pay for it. Being the cheap service it's a bit limited - some tracks only allow a 30 second preview, which is crap, but the music quality is superb for a streaming service - head & shoulders above Spotify, I think.

I probably won't renew it because I can't really use it on my phone with the crappy data coverage I have - that and it won't Scrobble to Last.FM either and being a stats freak that's quite important to me.

If you haven't taken up the free 30 day trial then give it a whirl, though, it's well worth it.
