I'm not a fan of Glee, but I did hear a few songs and he always stood out to me as someone with the best voice. When I first heard Glee's rendition of "No Air" I thought it was a black man singing because it was just that much soul, but nope it was Corey. I hadn't been following him so I had no idea that he was on drugs, but he seemed to hide it well. Geeze, R.I.P.
