Sort of an odd choice, but I suppose after Taemin covering Korn, anything is possible. In terms of popularity, I would have thought Poker Face, Bad Romance, Born This Way, and Edge of Glory would be first on the to-cover list (SHINee has already done Just Dance). I suppose, vocally, Bad Romance and Edge of Glory may be beyond Key.
Well, quick comments on the audio?
It is definitely prerecorded like every dance-heavy track that kpop artists perform as an “extra goodie”. Key’s voice was a little monotone and nasally than I liked, and they changed the melismas to fit in Key’s range, and most of the song was chopped up aurally using autotune.
However, this is just quick thinking about the audio. Key is rather a good performer, and judging by the way the fans were screaming, I should hold my tongue until a fancam surfaces.
