Kenny Chesney, Brad Paisley, Rascal Flatts, George Strait and Keith Urban stand nominated for entertainer of the year at the 41st Annual Country Music Awards (7 p.m., ABC). Paisley and Strait lead the pack with five nominations apiece, in categories including best male vocalist and both single and album of the year.

Among the evening’s many performances is an appearance by the Eagles, the popular country-rock group of the 1970s whose songs have continued to sell in the intervening decade as the Eagles have gone through a cycle of reunion tours.

The band has also been around long enough to profit from the many changes in musical format. It’s conceivable that a teenage Eagles fan could have purchased “Take it Easy” as a 45-rpm single in 1972 from a record store down the corner. He then bought it again as part of the “The Eagles” album. Or maybe he got it “free” for joining the Columbia Record Club, an organization that would hound him for the next 10 years. He might also splurge for an 8-track or a cassette of “The Eagles” to play in his car. A few years later, he might buy “The Eagles Greatest Hits,” one of the best-selling albums of all time.

By the late 1980s, a 30-something Eagles buff might feel compelled to upgrade to a CD because he thinks they are the new big thing and will “last forever.” Feeling flush and in his 50s and oh-so 21st century, that same fan might then download the song “Take it Easy” from iTunes – coming full circle to the purchase of the same “single” he bought in 1972.

To market their latest album, the Eagles have signed an exclusive deal with the world’s largest big-box retailer, an outfit that sells everything from rutabagas to widescreen televisions. You can’t find their new album in a record store. If you could find a record store.

¢ Few shows seem to revel in stereotype-casting as much as “Clean House” (9 p.m., Style). Or have as much fun doing it. “Clean” features a foursome of experts who help households that have become dysfunctionally cluttered. The gang consists of Niecy Nash, who plays the warm but sassy black fairy godmother to the hilt. She’s joined by Trish Suhr, a southern-belle cheerleader type who loves to shop; Matt Iseman, the jocular construction expert; and Mark Brunetz, the flamboyant interior decorator.

The sad cases on “Clean House” are drowning in stuff. Over the course of “Clean,” the team cajoles the family to sell stuff in a yard sale. The process of getting them to “let go” is long and arduous. Proceeds of the white elephant sale are matched by the show’s producers, and then Niecey’s team gives the home an extreme makeover, followed by a “reveal” to blindfolded subjects and gasps of joy and hugs all around.

¢ On “Mythbusters” (8 p.m., Discovery), Jamie and Adam determine if an ordinary household hot water heater could generate enough pressure to blow the top off the roof of a house.
