It's Not Quite "Teenage Dream," but It's Damn Close
One of the song highlights of Glee's 2 seasons has been Darren Criss singing Katy Perry's "Teenage Dream" in his first episode. Audiences responded, making it the biggest and fastest selling song the show has done, and pretty much instantly guaranteed Darren an permanent spot as a series regular (which will become official with season 3). The audience loves him, Ryan Murphy loves him, and Fox network (reportedly) loves him, so it makes sense that they're giving him screen time every chance they get. his latest is "Bills, Bills, Bills."
It's rare for a single character to break out in such a big way, but there have been a few. I break them down, here.
