what is a good social networking site for musicians and music lovers?

Bryan: what is a good social networking site for musicians and music lovers?
I am looking for (obviously) a good, or the best social networking site for musicians and music lovers. Something where music can be discussed and enjoyed as a whole. Pretty much like FaceBook and MySpace but for music. Anybody know of such a thing?

P.S.
I mostly listen to Pop/pop-rock/hardcore/post-hardcore music.
Thank you.

-Bryan.
