So spotify is an amazing free program they developed in sweden that enables you to stream basically any music you want- they don't have it offered in US, but if you follow the directions here, you can add it (its basically just using a british proxy to fool it into thinking you're in england):

after you have spotify, you might also wanna checkout the spotify playlists my boyfriend posted on his twitter: www.twitter.com/pallers

the "chill pop" one is amazing (:
