i tend to watch anime. i recently finished Naruto and not bothering to find a new one i started watching Family guy in stead. Family guy rocks...
a note on the Naruto one though, i rarely actually look at the screen when i'm painting, i just hear what happens in stead. So when i was watching Naruto (Japanese with english sub) i actually believe i've learned a lot of japanese! or... some... i think...
anywho. i listen to music, a LOT! i find jazz work good when painting. that or some slightly heavier stuff. not too heavy though. i rarely go any heavier than the white stripes or queens of the stone age. great music that is.
