place to stream music?

[JesA]

well in my computer class, we're allowed to listen to music on the internet. Everyone is satisfied but me....they can find their music (Soulja Boy, Jonas Brothers, Pretty Ricky) in one click, but i need a place where i can find MY music....like Origa, Salt n Pepa, Hikki. I've tried Playlist.com, but all i can find are the well known songs like with Utada, it's all First Love and Final Distance. Does anyone know of a site where i can LISTEN to a wide variety of music, other than Playlist.com


and we arent allowed on youtube or myspace
