I used to, until some fucker broke into my car and stole all my expensive import CDs, probably not even realizing what he was getting.
I realize the probability of such a thing happening is really low, and I could easily get around the problem by keeping my original CDs at home; taking burned copies to the car, and that I should be greatful that the asshole didn't just steal my car. But the whole experience left a bad taste in my mouth that lingers to this day.
Although I did just recently pick up a couple Shadow Hearts OSTs, so maybe I'm finally getting over it.
