Metallica almost certainly still got paid, so I doubt they care much. Blizzard is probably furious.

Maybe they'd need to be paid twice - is there a way to license the music for online streaming? And was it done as part of the contract in this case?

Metallica is probably not in it for the $ much these days. I'd wager it's more about ego, so this probably stung. Deservedly.
