Should Metallica still be in the Big 4?

Seriously, they're no longer thrash . The first two albums were strictly thrash, then when Master of Puppets came out, everything changed. Nowadays, they're pretty much hard rock and heavy metal, trying to retain their fame. No I'm not saying I hate Metallica, i luv em, but if they're not thrash anymore then they should give the spot to someone more deserving like Exodus or Kreator.
