I believe his point was to call attention to the following, deep into the review, which is another horror story about CBS (a la The Fugitive), where music replacement has seemed to become the norm:
" The show's opening theme song was a version of Billy Joel's "You May Be Right" sung by Southside Johnny, but on this DVD we get some instrumental music that sounds very cartoonish (so it does fit the artwork in the credits I guess), but no original theme. Ugh a theme song replacement!"
I can't blame the folks at CBS for yanking the tune. They have to pay for the use of the song 23 times. That adds up. While it's sad to see it zapped, that's just what happens cause Billy Joel's publisher won't cut a deal - see Bosom Buddies.
While this sucks, this hurts the singer more than the show. Yeah, the show will suffer for it, but the singer hurts both ways: if their music isn't used, then they get no money. Then people are forced to go to other routes to get the show and the singer still gets no money.
It's a damn shame, but the only thing that will come out of it is a lot of singers not getting royalties for shows at all. If that's the game they want to play, on their own head be it.
