I wonder if Metallica really had an issue with how their music was used, or rather that their music was used. I definitely put them in that category of musicians (Prince, the Beatles, the Smashing Pumpkins) who are overly protective of their music.
The same genius - GENIUS - mashup artist who made the POTUS sing LMFAO is back, this time to help him sing THE SONG THAT WON'T DIE. SERIOUSLY. IT'S BEEN FUN, INTERNET, BUT YOU CAN MOVE ON TO A DIFFERENT POP JINGLE NOW.
