Louie Louie
Here's a playlist of all 40 versions of the classic garage song Louie Louie that I could find in Spotify, after removing a few duplicates. It makes for great listening while training. The original version (or as close to it as makes no difference) is in numbers 9 and 10 on this list, while the version that really got the ball rolling is by The Kingsmen, number 3 in this playlist.

Astonishingly, this song was the subject of a 31 month FBI investigation into supposedly obscene lyrics. The FBI concluded that the lyrical content couldn't be divined from listening to the song. More at Wikipedia's page on Louie Louie, and the web page devoted to Louie Louie.
