Casey Abrams Sings Nirvana On Idol

Well, I didn't see this when it went down last night, but my phone blew up when it happened. Casey Abrams sang "Smells Like Teen Spirit" last night on American Idol. If you've ever seen him, you know the guy is probably the most talented contestant that has ever been on American Idol as far as musical talent goes...but...NIRVANA? I don't know, is it a good thing he did this? Was it a good performance? Is Kurt Cobain rolling in his grave? Watch the video and comment to let us know your opinion. Oh, just skip to about the 2:10 mark, that's where the performance starts.
