What do you think of the Music Hub App?

[Persill]

I just started using this and it seems just great. I'm a huge fan of music, have tons of it and just the idea of being able to listen to anything on demand is great. What does everybody think of this app? Pros and cons? is there any other app that works better? I'm using the trial version and thinking about subscribing for $10/month; the sound quality on the Note is very impressive =]
