Well sometimes it's really about convenience. I realize that somedays I want to listen to a song but don't want to go and buy the single in the store, so what do I do?...DOWNLOAD!! I see a lot of my friends borrowing stuff from one another and since they don't want their friend borrowing a legit copy, they'll burn him/her a copy of whatever they wanted.
Piracy is going to be very difficult to get rid of, but I think one day it will be done..Then again the day that piracy is ended something bigger and more illegal will be happening..
