[/caption]For the first time ever, a contestant on American Idol sang a song from '90s grunge-gods Nirvana. Casey Abrams, who missed a show last week when he was hospitalized for a bowel condition, kept the drama going on Wednesday night's telecast with his out-of-left-field selection of  "Smell's Like Teen Spirit."

The reactions from judges Steven Tyler and Randy Jackson to Abrams' performance were very positive. Jennifer Lopez was a bit less enthusiastic, although she stated she still "loved" Abrams.
