can someone explain in one sentence what myspace is all about and more importantly do i need it?
Myspace is pretty music-centric - as far as promoting new music goes, Myspace is an utterly revolutionary tool, and most of the bands and assorted musicians I know have more or less abandoned their old websites for their Myspace pages. Still, a lot of people who don't have something to sell also like playing with Myspace.
Oh, did I mention
http://www.myspace.com/danaimmanuel ?

Oh, and there is a strange thing that exists at
http://www.myspace.com/blondepoker . Should you be interested...
