The Rapper: Mac Miller
The Lawsuit: Lord Finesse sued him in 2011 for sampling his "Hip 2 Da Game" beat for his mixtape track, "Kool-Aid and Frozen Pizza"
Why It Was Dumb: According to Mac, Finesse never cleared a sample that was used on his beat. So in actuality, Finesse was just as guilty—if not more guilty—of jacking a beat when he created "Hip 2 Da Game." Cooler heads eventually prevailed and these two settled out of court.
