I download tons of mp3's, and if I like what I hear I'll buy the Album. I believe loads of underground artists are making some money and getting a little more fame thanks to the mp3 share community.
When it comes to movies I couldn't care less, if movies wasn't released ages earlier in the USA I would probably go to the cinemas more often but when I can download a DVD Rip of a movie I want to see a month earlier than it's shown on the cinemas here in Sweden, it often ends that way.
And when it comes to Warez, I haven't paid a Dime for the Windows versions I'm using at home, and I have a Flash cart for my GBA, but I still try to support the software which I think deserves it, and have promised myself to buy the software I'm using for my AmigaOne, if I ever can afford one.
And sorry if my english isn't the best :-o
