Crystal Bowersox Performs 'Come To My Window' on 'American Idol'

Crystal Bowersox has -- little surprise -- picked a Melissa Etheridge song, Come to My Window.

"It's a song about, like, passion and love and things like that."

She's in full-on busker mode for this one, starting out playing harmonica and acoustic guitar. And, despite all the people who have likened her to Etheridge this season, she kind of pales in comparison. It's a good-enough performance, especially after the way the judges raked Casey over the coals, and it probably gives a great sense what Crystal will look and sound like once the show's done. But Crystal's voice simply doesn't have Etheridge's raw power, and the harmonica playing, which also ends the song, comes across as awkward.
