CAUTION: song spoilers...

It's rock and roll night on American Idol, and TMZ has the song selections. (No mention of performance order, not that it matters much when we're down to four kids.)

So if you don't want to know what they're singing, avert your eyes. If you do want to know, keep reading.

Castro: Tambourine Man (Bob Dylan) and I Shot the Sheriff (Eric Clapton)
Cook: Baba O'Reilly (The Who) and Hungry Like a Wolf (Duran Duran)
Archuleta: Stand By Me (Ben E. King) and Love Me Tender (Elvis)
Syesha: Proud Mary (Ike/Tina Turner) and A Change is Gonna Come (Sam Cooke)

This could be interesting. See you then.
