^^It's really no different than JC singing "The Game Is Over" on his club tour. Yes, they are a solo artist, but people are fans of Justin partially because of his time in NSYNC and I think it's only fitting he and any of the other guys pay tribute to that. Justin's damned no matter what he does, because if he didn't sing a few NSYNC tunes, people would say that he was neglecting his roots and ashamed of being in a boyband.

As for the main topic, if you hate someone as Jayne confessed TWICE, you're probably going to be pretty biased on anything they do. I love Justin but I can recognize when he's not good at something. He was pretty bad in some of his other movies, but I respect him as an actor for taking smaller parts and at least attempting to learn and improve.
