David and David traded musical punches on Tuesday's "American Idol," and FOX scored a unanimous ratings decision.

FOX's household numbers -- 10.9 rating/17 share -- were only a little better than ABC's 10.6/17. However, FOX had about 3 million more viewers (19.34 million to 16.26 million for ABC). CBS finished a solid third at 9.2/14. NBC was well off the pace at 3.0/5, and The CW drew a 1.4/2.

"Most Outrageous Moments" earned a 2.5/4 for NBC, which was good enough to beat a "Reaper" encore on The CW.

The "Dancing with the Stars" finale, 12.3/18, moved ABC into the overall lead at 9 p.m. A second hour of "NCIS" improved to 11.0/17 on CBS.
