1) “iHeartRadio Music Awards” (8-10 p.m. today, Fox) and “CMT Music Awards” (8-11 p.m. Sunday, CBS). The week starts and ends with music; some performers — Lainey Wilson (shown here) and Jelly Roll — will do both shows. Fox also has Justin Timberlake, Green Day, TLC and an award for Cher. CBS has Keith Urban, Trisha Yearwood, Sam Hunt, host Kelsea Ballerini, Cody Johnson, Old Dominion and more.
2) “Elsbeth” return, 9 and 10 p.m. Thursday, CBS. Here’s Elsbeth at her best – all bright colors and bright smiles, clashing with dark-hued New Yorkers. That peaks in the first hour, with Linda Lavin, 86, as a despotic co-op head. Soon, Elsbeth is probing board members and a realtor (Jane Krakowski). It’s a clever hour, followed by one with the star of the “Lavish Ladies” reality show found dead.
3) More CBS returns. As the basketball tournament wraps up, some of CBS’ top shows return from a two-week break. On Thursday, “Young Sheldon” has grandmothers at odds over the baby’s baptism; then “Ghosts” sees Trevor’s scheming brother arrive at the inn. On Friday, “SWAT” and “Blue Bloods” surround a “Fire Country” crisis: A “fire tornado” brings a deadly mix of heat and wind.
4) “Mr. Bates vs. the Post Office” debut, 9 p.m. Sunday, PBS. This was a real-life battle between the little guy and the system: In postal sub-stations all over England, the people in charge were told that they owed money … and that no one else had trouble with this. Then they got together and suspected the new computer system was at fault. Toby Jones is terrific, in a stirring, three-week mini-series.
5) “American Idol,” 8-10 p.m., today and Sunday, ABC. “Idol” expands to twice a week, with the young singers facing quick changes. Tonight, they have their first time with a full band; then the judges choose the top 24. (This comes while NBC’s “The Voice,” also 8-10 p.m., pauses for a “best-of” look at auditions and “battle rounds.”) On Sunday, “Idol” takes its 24 for two shows in Hawaii.
6) “Lopez vs. Lopez” season-opener, 8 and 8:30 p.m. Tuesday, NBC. As “Idol” expands, “The Voice” trims to Mondays-only … leaving a Tuesday void. “Night Court” and the clever “Extended Family” are gone, replaced by this dim comedy. (The first episode is clumsy; the second shatters the show’s concept.) That’s followed by “Weakest Link” (with “Days of Our Lives” stars) and “Password.”
7) “Walker” season-opener, 8 p.m. Wednesday, CW. When CW dumped its dramas, four survived: “All American: Homecoming” is expected this summer, the final “Superman & Lois” season is this fall and the others arrive now – “All American” (8 p.m. Monday) and this show, with a packed hour. There’s joy (on Walker’s birthday), action (Cassie leads a tough shoot-out) and fear, over a killer’s return.
8) “Sight Unseen” debut, 9 p.m. Wednesday, CW, rerunning at 9 p.m. Friday. A sharp police detective finds she’s going blind. Hesitant to tell her colleague, she grasps for a solution: Her body-cam is linked to an agoraphobic guide, who gives instructions via her earpiece. Part of this feels contrived, especially with her refusal to tell anyone. Still, the characters are solid and the cases are strong.
9) “Saturday Night Live,” 11:29 p.m., NBC. The next couple weeks could bring huge audiences. On April 13, Ryan Gosling hosts; first is Kristen Wiig, with Raye as music guest. In seven “SNL” years, Wiig became the show’s star. She left in 2012, but this is her fourth return as host. She also stars in the glittery “Palm Royale,” which has its fifth episode (of 10) Wednesday on Apple TV+.
10) ALSO: PBS profiles Julius Caesar at 9 p.m. Tuesday and William F. Buckley at 9 Friday. The brilliant “Resident Alien” ends its season at 10 p.m. Wednesday on Syfy. Basketball’s final four teams meet at 6:09 p.m. ET Saturday on TBS, TNT and TruTV, And Sunday has the season-opener of “When Calls the Heart” (9 p.m., Hallmark) and the series finale of “Curb Your Enthusiasm” (10, HBO).
