American Idol's finalists tackled 10 R&B/Soul tracks last night.

Crystal Bowersox shined on "Midnight Train to Georgia," while Lee DeWyze turned the Cornelius Brothers' "Treat Her Like a Lady" into a contemporary rock tune.

Andrew Garcia got his groove back with an acoustic rendition of Chris Brown's "Forever," while Siobhan Magnus took heat for Chaka Khan's "Through the Fire."

Michael Lynche got raves for a performance of India.Arie's "Ready for Love," and Casey James got high marks for covering Sam & Dave's "Hold On, I'm Coming."

Aaron Kelly and Katie Stevens didn't do much with their material, and Didi Benami and Tim Urban might really be the ones sweating on Wednesday's results show.

The night's best:

Michael Lynche, "Ready for Love"

Lee DeWyze, "Treat Her Like a Lady"

A job well done:

Crystal Bowersox, "Midnight Train to Georgia"

Andrew Garcia, Forever

Casey James, "Hold On, I'm Coming"

Not great:

Siobhan Magnus, "Through the Fire"

Aaron Kelly, "Ain't No Sunshine"

Katie Stevens, "Chain of Fools"

In danger: 

Tim Urban, "Sweet Love"

Didi Benami, "What Becomes of the Broken Hearted"
