Like AXE2577 said, I hate with a passion talentless twats ripping off great tracks and passing them as their own. Actually makes me want to slap someone when I here a favourite EDM track being tarnished by some one with zero talent. In addition to this I also hate it when a (c-)rap artist uses an artist on their record who can actually song very well. It's usually this good singer that sells the record with most of the credit going to the rapper. No examples, they don't deserve to be mentioned.
Great tip. Thanks for posting.
