Elvis would have been 80 today, so grab a Fool's Gold sandwich and kick back with some classic Presley tunes. Spotify has concocted a whiz bang web app called The Elvis Influence that connects the dots between any artist and the King. It's kinda like Six Degrees of Kevin Bacon, but with Elvis the Pelvis (and a pound of bacon).
If you feel like getting your Elvis groove on, Spotify has a special birthday list in honor of the King's birthday, which you can check out here. So, put that in your pipe and smoke it.
