Music to frag to

One of the 360's improvements over the original Xbox is the ability to play whatever music you like during games (provided the Xbox can access it, of course). This can lead to hilarious comedy moments such as a Perfect Dark Zero stake-out to the Benny Hill theme, or using Madness' "Driving in my Car" as the backdrop to a PGR3 showdown.

Since there's unfortunately no audioscrobbler-like service to track what your friends are listening to as well as what they're playing, we'll have to resort to the old-fashioned way: asking. What music's top of your Xbox 360 playlist?
