Actually it goes a bit more like this -
One person submits a cool tune that took him a lot of work, and someone else posts 45 seconds of garbage shredding. Then everyone listens to the two and clicks like mad on the latter, all the while shouting, "Ohhhh a lot of pointless 80's hairmetal shredding!!!! . . . Woooowwww!!!"
Yeah, I suppose I'm a bit bitter.
