Hi Daniel,
I was listening to Captain Beefheart the other day, and realized that Tom Waits is one of the few places you can hear his influence: Swordfishtrombones. And for Leonard Cohen, too, there's a lot to choose from. I like the song "Hallelujah", in which I am not alone. John Cale does a nice cover of it.

On my speed question, I ran into Bo Diddley's "Roadrunner" only yesterday, and thought to post it. It's a contender:
