Who has sold more albums Metallica or Blink 182?

Metallica - I think it's an insult to even put 50 cent in the same sentence with Metallica

metallica have been around since the eighties, 50 cent has only been famous for a few years, metallica are one of the most popular heavy metal bands and have made a whole bunch of albums including one of the most popular heavy metal albums ever called master of puppets. 50 cent has done like 2 solo albums ? and albums with G unit and probably helped produce and featured on whichever G unit members made albums, and he didnt get shot 9 times, he got shot AT 9 times but only got hit a few times, so I would say metallica
