I'm sure I'm dated in linking to this, but I highly suggest you give a listen to Hard n' Phirm's "Rodeohead" if you either like Radiohead or listen to bluegrass. Or both. If you like Radiohead you'll find it amusing. If you like Bluegrass, you'll be surprised at how well done it is. If you like both, you'll be surprised at how well tracks from Kid A (amont other albums) translate to bluegrass.

After linking to that Shatner song previously, I may have to start another semi-random feature: "Amusing Novelty Song of the Moment."
