I write music for (mostly student) short films, games and (very rarely, unfortunately) commercial stuff like ads/documentaries/etc. It's fun stuff! I have an absolutely ridiculous amount of software now, and it's pretty good. It always makes me laugh when people ask how I got the budget for a brass section XD
On top of that, I also play guitar, bass, drums, keyboard and sing. I used to sing in a kind of traditional metal band, that was really kind of an affectionate parody. At the minute I'm recording the most depressing alternative rock album ever made :']
As far as the unfortunate loudness war goes, I do hate how I have to squash my pro stuff for the reasons MoS mentioned. As far as my personal projects go, though, fuck that shit. I realize that far fewer people will be able to listen to my stuff if I don't, but I don't care. I'm recording that album for me, first and foremost, other people listening to it would just be nice.
