Darren Criss joined the cast of Glee in the episode “Never Been Kissed” as Blaine Anderson, a gay student at a rival school. He is now a recurring character. Darren’s first song on Glee, “Teenage Dream “, hit number 1 on the Billboard charts, selling 214,000 singles in its first week. It was the first time a Glee track had reached the #1 spot, and is the fastest selling Glee track to date. He followed this trend with other songs he sang in later episodes; “Baby It’s Cold Outside,” “Bills, Bills, Bills,” “When I Get You Alone,” “Silly Love Songs,” “Hey Soul Sister,” “Animal,” “Candles,” and “Raise Your Glass;” most which have reached the top ten on iTunes.
