Television critic Mike Hughes has his top picks for tonight, with some notes on other shows you might be following.

TONIGHT'S MUST-SEE

"American Idol," 7 p.m., Fox.

"There are no second chances," Kara DioGuardi recently warned "American Idol" contestants.

Now some of them get ... well, a second chance. Don't believe everything you hear on TV.

This is the "wild card" round, in which the judges consider eight previously rejected contestants. Three will get spots in the final 12.

Tonight, judges hear one more song from four women (Megan Joy Corkrey, Jesse Langseth, Jasmine Murray and Tatiano Del Toro) and four men (Anoop Desai, Matt Giraud, Von Smith and Ricky Braddy).

They might go for balance. So far, the nine finalists include six men and three women; they include six whites, two Latinos, only one black. Now comes one more shot at diversity.

"CSI: Crime Scene Investigation," 9 p.m., CBS.

The last two years have been impressive for Taylor Swift. She's had three singles reach No. 1 on Billboard's country chart, eight reach the top 16 on the overall chart. Her "Fearless" album topped both charts; it was No. 1 overall for 10 weeks -- the longest run in a decade.

That's not bad for someone who's 19. Now comes her acting debut.

The case involves a murder at a seedy hotel -- the third there in a year. Swift plays a teen who has known Nick previously; her song, "You're Not Sorry," is also featured.

OF NOTE

• "Burn Notice," 6 a.m. to 3 p.m., USA Network. Leading into this above-average show's season finale (at 10 p.m.), here's a block of reruns.

• "Survivor," 7 p.m., CBS. The first clear alliance forms, CBS says, with four people convinced they have things figured out. Meanwhile, this hour has what "Survivor" calls its toughest test of strength and endurance.• "Ugly Betty," 8 p.m., ABC. The landlord suddenly puts Betty's family home up for sale .Now there's a scramble to come up with the money; Ignacio even enters a cooking contest, going against a celebrity chef (played by Steve Schirripa of "The Sopranos").

• "Grey's Anatomy" and "Private Practice," 8 and 9:02 p.m., ABC. Now that their "crossover event" has ended, these shows revert to reruns. That starts with a minor crossover: Addison visits her old "Grey's Anatomy" hospital and is surprised by the changes in personal lives. In the next hour, she returns to her current show and works with Charlotte to save a comatose woman and her unborn child.

• "The Office," 8 p.m., NBC. Michael meets a mystery woman at a valentine event. Also, Jim and Pam are banned from the office for being too openly affectionate.

• "Burn Notice," 10 p.m., USA Network. In the season finale, Michael gets his showdown with Carla, played by "Battlestar Galactica" co-star Tricia Helfer. Also, he learns secrets about Victor, played by former "Stargate" co-star Michael Shanks.

• "Randy Jackson Presents: America's Best Dance Crew," 10 p.m., MTV. Here's the season finale, with a champion named. All nine competing teams return.

• "ER," 9 p.m., NBC. In its final season, this show turns to a time-tested formula -- an hour that pretends to be a documentary, with characters talking to the camera. That happens on a busy night in which Morris' girlfriend, a cop, is rushed in with gunshot wounds. Also, Sam struggles to get along with her mom, played by Amy Madigan.
