Now I know why CM is so good...another Ministry fan
I can't listen to music while mapping, well, not my usual music cuz it makes me start dancing or thrashing. I actually half watch sports, history channel, science channel, military channel, discovery channel, and a bit of cnn and cnbc. At my real job, I have a tv there too so it's usually the aforementioned things with a smattering of travel channel (Anthony Bourdain), food network (I like to laugh at the extravagant means they go to in order to make a meal...and usually ruin it), and comedy central (you can probably guess which two shows).
When I do listen to music it's for drawing my stained glass and it's Classical (Bach, Schubert, etc.), metal (Metallica, Korn, Marilyn Manson, etc.), industrial (Ministry, Skinny Puppy, etc), or old techno/rave/house (Lords of Acid, Electric Hellfire Club, etc), and I don't know what category they go in but I love 311 and my guilty pleasure is 80s retro pop (Come on Eileen, Safety Dance) When I really need a creative push, though, it's Mozart's 25th, Beethoven's 9th, Wagner's Ring cycle, Bizet's Carmen, and Orff's Carmina Burana.
