For everyone who is yet to discover this, please take a moment to appreciate its genius.

Pandora

Pandora is a site that will stream you music based on the songs you love. It's based on work by the music genome project, whose aim is to classify the component elements ("genes") of music. By entering a song, it's genome, it's music "dna" is matched to the database and it streams similar songs with a similar genome to the entered song. You'll love it, trust me. Enter "Fall Out Boy" and it will generate you a radio station of similar songs. You'll discover new artists and be happy forever more.

Worthy.
