Usually some kind of rock or metal. ZZ Top and Poison are my usuals, or whatever random metal titles I have floating around on my MP3 player (Battle Beast, Megadeth, etc.) I also will occasionally blast swing/electro-swing (Big Bad Voodoo Daddy, Caravan Palace, Parov Stelar) or some of those delightful hits from the 90's (Los Del Rio, Ace of Base, etc.), and whatever genre Oingo Boingo falls into (new wave, I think). I do my best to resist the urge to drive by funeral homes while playing "No One Lives Forever" out my window because I'm a decent human being. Sometimes.
