When Tony Soprano finally—all right, possibly—got whacked to the sounds of Journey's "Don't Stop Believin' " in June 2007, America had mixed reactions. But the show's viewers all agreed that TV's greatest mafia boss and music's shiniest power ballad were linked for life, seared into pop culture consciousness.

If someone had predicted that two years later, a prime-time comedy about a high school choir would revive Journey's biggest hit yet again, they would have been laughed off the lot.

But here we are in 2009, and How Fox And Columbia Used 'Glee' To Rewrite The Script On TV Music. s—daft jocks, pregnant cheerleaders and divas in training—has done just that. The show's pilot episode, which premiered May 19, not only introduced viewers to Rachel Berry (Lea Michele), Finn Hudson (Cory Monteith), Mercedes Jones (Amber Riley) and the rest of the show's choir gang, but also to their recording of "Don't Stop Believin'," which replaces Steve Perry's epic yelps for Monteith's boyish croon.

Then it got viewers to buy that recording on iTunes: Through the week ending Oct. 18, the "Glee" version of the song has sold 522,000 downloads, according to Nielsen SoundScan. In the week following its TV debut, it sold 177,000 downloads and entered the Billboard Hot 100 at No. 4—higher than Journey's version ever charted.

Several TV shows move music fans to buy songs they hear, but "Glee" gets them to buy new versions by the program's cast. Columbia sells the recordings on iTunes, and the label has had a striking amount of success.

"In all the years that I've been in the business, I've never worked on anything quite like this," says Geoff Bywater, head of the music department at 20th Century Fox Television. "It's a real cultural phenomenon that you can just feel. We've got people who are going to have great acting careers and recording histories for themselves in the future."

Collectively, 20 titles by the "Glee" cast have sold...
