If you want to know what floats Dave Grossman's boat right now you could rifle through his garbage, or alternately read this little Gamasutra Q&A session.
Sounds: I like a little of everything, but at the moment I seem to be particularly listening to lounge music and funk. I also really enjoy unusual covers of usual songs ? I made a collection of versions of Ring of Fire, for example, which I use to test people's patience. My current favorite band is Cocktail Angst, a dazzling lounge combo with Latin overtones and a sense of humor, who unfortunately stopped playing together last I heard.
