I really like it so far. It's getting better at recommending music and it's so nice to listen to new music all the time. I don't think I've stopped listening to music since I signed up. It's almost addictive actually!

I am more interested in music availability and quality, as well as usability of the service in general, than recommendations. I almost never listen to music that is recommended to me unless the recommendations come from good friends.
