Why I Love Weird Al
"Don't Download This Song" is an original song, but is obviously a parody of 80's fundraiser songs. (Think "Do They Know It's Christmas?" or "We Are the World".) The song pretty hilarious, and so you should probably give it a listen. (But don't download it illegeally! You will die of the irony.)
Even though he wrote "Don't Download This Song" Weird Al has expressed an amount of disdain for p2p music downloading. Since he is a such a prominent comedy song artist, a lot of songs that aren't his are attributed to Weird Al. Many of them actually contain explicit content and Weird Al, who is proud to have clean lyrics, feels that this is bad for his artistic image.
Imagine that, and artist how is actually concerned with the effect of p2p downloading on his artistic reputation (and not the money he makes!) Not only does Weird Al have a more legitimate complaint about p2p downloading, he also isn't a bitter old hag about it. (Metallica comes to mind.)
Cause you start out stealing songs
Then you're robbing liquor stores
And selling Crack
And running over school kids with your car
-- Weird Al Yankovic, "Don't Download This Song"
He was pretty much Napoleon Dynamite as a kid.
