It wasn't so much the fact that it was a random blog comment, but what was posted added up with what I already knew. Though now that I think about it, that would be a VERY last-minute change; maybe it had nothing to do with the Kurt Cobain incident after all.
EDIT: See for yourself
It probably had to do with them playing GH:WT and seeing Ozzy singing paramore songs. That was pretty bad.
I love how in the DS version you can build characters using the parts from unlocked celebrities. It would of course be super weird and creepy in a more realistic game, but it fits perfectly in a Lego game and the console versions suffer from the lack of that feature.
The fact that you can't play the Queen DLC in setlists or storymode is still nonsensical and frustrating, and I hate that people still casually spread the falsity that they can be "unlocked" at any point, because they can't. The idea that the game was intended to have them be unlockable but then that feature was removed... makes more sense than anything I've heard so far.
