I do, yes. I didn't buy anything much new, either, except a few more movie soundtracks. I've essentially ripped all my movie soundtracks to mp3, edited out the songs I don't like, put the entire thing (for a given campaign, anyway) on CD-R and toss it into my DVD player (we play in the front room) on shuffle and turn the volume down fairly low.
The advantages of doing it this way? Lots of variety of music without me having to think about it much, and orchestral soundtracks from movies aren't usually very distracting. I can also get the "themes" and tone of the campaign overall on a single CD-R, which I like. I can't, with this method, however, have music that is appropriate for the actual scene that's going on. I don't mind that too much, though, as that'd be too much work for me to worry about as a GM anyway.
My current campaign, which is a kind of pulp-horror fantasy thingy uses music from Bram Stoker's Dracula, End of Days, From Hell, Sleepy Hollow, Minority Report, the Last Samurai, Last of the Mohicans, the MummySigns, Sum of All Fears and a few other soundtracks as well, again edited out to remove songs that I don't want (notably the Annie Lennox Dracula song...)
For a more straightforward fantasy, I still use a lot of those, but add in the Stargate, and the three Lord of the Rings soundtracks, and the Pirates of the Caribean soundtrack and Conan the Barbarian, Gladiator, etc.
