OK, these numbers have fantastic joke value. But shouldn't we leave the unintentional humor to the amateurs? And don't these efforts detract from movie stars who actually have musical talent?
Certainly, many movie stars can sing. Why reward those who can't? It's no surprise that William Hung's albums -- "Inspiration" and "Hung for the Holidays" -- both cracked the Top 40 of the Billboard 200, making "American Idol's" most famous reject also one of its most successful recording artists.
The question is: How many William Hungs does the world need? And if we're going to reward someone for being a no-talent, isn't there someone more deserving than Trump? I sing badly, and I have no shame. Hint, hint.
"Emmy Idol" also raises another troubling problem: It only encourages the likes of William Shatner to sing more. Last year, Ben Folds, Aimee Mann, Joe Jackson and Brad Paisley lent their talent to the release of "Has Been," Shatner's most ambitious (and aptly titled) album yet.
While the results might not have been too pretty, we must nevertheless appreciate Shatner's impact on the recording careers of so many non-singing celebrities. Would Don Johnson, Eddie Murphy, Keanu Reeves, Alyssa Milano, Maureen McCormick, Billy Bob Thornton, Dennis Quaid, Corey Feldman, Kevin Bacon, Russell Crowe and Steven Seagal have had the courage to release albums over the years, despite questionable musical talent?
Thanks to Shatner, we can relax to Bruce Willis -- a man who can barely talk -- as he mumbles his way through "Under the Boardwalk" and "Secret Agent Man." Feeling sad? Minnie Driver's weepy version of Bruce Springsteen's "Hungry Heart" is there to comfort you.
As the android Data on "Star Trek: The Next Generation," Brent Spiner can trace his musical lineage even more directly to Captain Kirk. On his 1991 album, "Ol' Yellow Eyes Is Back," Spiner interprets pop standards like "Embraceable You" and Cyndi Lauper's "Time After Time."
You never know who will make it on the Billboard charts. David Hasselhoff -- who is now legendary in the United States for being a legend in Germany and a has-been at home -- parlayed his "Baywatch" fame into a multiplatinum recording career.
Historians will note that on New Year's Eve in 1989, when the Berlin Wall fell, Germans at their reunification celebration were singing Hasselhoff's No. 1 hit, "Looking for Freedom."
Hasselhoff even headlined a show from atop the wall to mark the occasion -- and was so hot, he was voted "Most Popular and Best Selling Artist of the Year," beating out Madonna and Michael Jackson.
Hasselhoff was such a phenomenal success, even KITT, the super-intelligent talking sports car from "Knight Rider," began looking into a record deal.
In fact, I wouldn't be surprised if Hasselhoff and KITT teamed up for a duet on Sunday's "Emmy Idol." They've both got great pipes.
