Best-bets for Dec. 14: A surge of music

1) “The Voice” finale, 8-10 p.m. NBC. This is a big music night, with performers — see below — including Billie Eilish (shown here), Kelli O’Hara … and the final five for “Voice.” Blake Shelton has two singers – Jim Ranger and Ian Flanigan – in the running, with one apiece for Gwen Stefani (Carter Rubin), John Legend (John Holiday) amd Kelly Clarkson (DeSz). Tonight’s performances rerun at 8 p.m. Tuesday, with the two-hour finale at 9.

2) “iHeartRadio Jingle Ball,” 8 p.m., CW. Each year, this offers lots of pop stars and noisy fans. Now the noise is muted, but there are plenty of stars, performing from home. They include Eilish, Harry Styles, Dua Lipa, Sam Smith, Doja Cat, Shawn Mendes, Lewis Capaldi and The Weeknd.

3) “Christmas With the Tabernacle Choir,” 9 p.m., PBS (check local listings). Now for the precise opposite of those intimate concerts. The Choir does each concert a year in advance; now we remember what life was like in December of 2019 – big and fun and … well, REALLY big. There’s a 360-voice choir, 100-piece orchestra and 20,000 people in the audience. Kelli O’Hara, a Broadway Tony-winner, sings magnificently and Richard Thomas does readings.

4) “The Bachelorette,” 8-10 p.m., ABC. Tayshia Adams still has seven guys to choose from … or maybe eight. Last week, Bennett Jordan apologized and asked to continue; she said she’d think about it. Now we’ll see what she does about that – and more.

5) “Nurses,” 10:01 p.m., NBC. Like “Transplant,” which ended its first season last week, this is a Canadian medical drama with likable people. Unlike “Transplant,” it tries too hard; this episode, the second, has four different characters spilling life secrets. And for the second straight week, an argument between Grace and Ashley seems contrived. Strip away the overkill and you have a solid drama
