The thing is, Key's actually not even a bad singer unlike Kwanghee. Kwanghee just cannot sing. During debut days, Key was the bridge between the good singers Jonghyun and Onew and the not-so-good singers Minho and Taemin. He CAN sing and he's proved it in SHINee's first few releases. He can go up against Jonghyun and hold his own during "Romantic," for crying out loud. What's saddening is that he just started not caring about honing the skills he DOES have. Taemin, on the other hand, did, and his improvement just highlights Key's deterioration even more,
