MP3s I find somewhat more understandable. A lot of times it's an individual song you like but you aren't going to go buy the whole album. Okay, who wants to pay 15 bucks for a hard copy of a single song? Nobody. Granted, now you can buy songs online and stuff, but I guess that's where there's a disconnect for me. I don't do MP3s and stuff anymore, really, so my brain is still stuck back in the days when Napster was free and you could download gigs of random crap you didn't need.
Meh. Anyway, I've never condoned piracy or stealing, but for some reason it gets to me more with certain things than others. Maybe those distinctions are arbitrary in the end, but people copying movies just gets on my nerves.
