1. "American Idol," at 8 on Fox, will reduce the Top 9 to the Top 8. Based on Wednesday's show, another guy is likely to go. Lazaro was probably the weakest, but he has a strong face base, which means Paul or Burnell could be ejected. Devin had several advantages: He sang last, and he was the best of the guys. Among the women, Janelle got a boost from going last and giving a beautiful performance. Her subtlety was a contrast to the full-throated performances by Kree, Candice and Amber. Also tonight, Ne-Yo and "Idol" runner-up Jessica Sanchez perform her single "Tonight." "Idol" alum Casey Abrams will perform "I Saw Her Standing There."
2. "Glee," at 9 on Fox, focuses on songs that are guilty pleasures. Those songs include Barry Manilow's "Copacabana," Abba's "Mamma Mia," Wham's "Wake Me Up Before You Go-Go," Bobby Brown's "My Prerogative" and Radiohead's "Creep."
3. If you loved Lisa Edelstein on "House," you'll probably want to give "Scandal" a try at 10 on ABC. Edelstein plays a CEO and the mistress of a nominee for the U.S. Supreme Court. Edelstein's character is represented by Olivia Pope (Kerry Washington), and that will create problems for the White House.
4. Meredith frets about her unborn child on "Grey's Anatomy" at 9 on ABC. The doctors also learn some unpleasant truths about owning a hospital.
5. "The Vampire Diaries," at 8 on The CW, flashes back to the 1970s in New York City, which wasn't a golden time for the Big Apple. Remember "Death Wish" and "The French Connection"? The networks will throw up a lot of new fare against basketball. NBC offers "Community" at 8 and two episodes of low-rated "1600 Penn" at 8:30 and 9:30. ABC brings back the regular "Wife Swap," not to be confused with the celebrity version, at 8.
