Seriously, fuck these people! That is a terrible decision.
Even seeing Lin there won't be satisfaction (heh? heh?) enough.
I wish I cared more, but the songs are always my least favourite part of the show anyway so I couldn't care less who sings them (and I'm still annoyed about the LLL songs they chose to submit, would've been more exciting to see either 'Another Day of Sun' or 'Someone in the Crowd' on stage). The Audition song definitely won't have the same effect as it did in the film though.
My own my mother thought I was a monster... she was right of course but it still hurt!
