NBC won Monday in the demo and total viewers with The Voice again winning the singing competition derby to finish as the night’s No. 1 show in both metrics. But the 8-10 PM Voice (1.5, 8.28M) dropped a tick, while ABC’s two-hour American Idol (1.4, 7.59M) inched up, producing the season’s closest head-to-head finish for the two series.

At 10 PM, NBC’s Good Girls (0.9, 4.14M) took the hour in the demo while ABC’s Crossing (0.7, 4.24M) snagged the top spot in total viewers.

James Corden’s annual The Late Late Show Carpool Karaoke Primetime Special (0.8, 3.84M) improved in the demo but slipped in overall audience compared with last May’s broadcast, when its lead-in had been the documentary special Princess Diana: Her Life, Her Death, the Truth.

Time time, CBS tried fueling Cordon’s music-and-celebrities special with two hours of hit comedy repeats, starting at 8 PM with The Big Bang Theory (1.0, 6.41M), followed by two Young Sheldon episodes (1.0, 6.06M; 1.0, 5.86M) and another Big Bang (1.0, 5.55M).

Opposite all that singing, Fox’s Lucifer (0.7, 2.82M) stayed steady week to week, while The Resident (0.8, 3.92M) dipped. So did tjhe CW’s Supergirl (0.4, 1.38) in a series demo low, and iZombie (0.2, 710K).

NBC (1.3, 6.90M) took the night, followed by ABC (1.2, 6.47M), and CBS (0.9, 5.26M). Fox (0.7, 3.37M) followed, then CW (0.3, 1.05M).
