Geez... I guess I need to quit bitching about my job, then. I test music software. It's not all fun and games, but it's definitely a cut above, say, accounting software.
I get to play with all of the latest synths, plugins, and other toys. I keep a guitar in my cubicle, and I even get an excuse to play it on the clock occasionally. I'm salaried, and the money, while not spectacular, is decent.
The major pitfall, other than the usual BS that goes on in software development, is what FngKestrel said... it takes a lot out of you. Someday, I'd really like to get into doing sound design. So far, though, I haven't had the discipline to force myself to sit down and jump into it. After staring at audio waveforms for 8-10 hours a day, the last thing I want to do is spend my free time in front of an audio app.
