This should seal Darren Criss’ deal to become a regular on Glee. The show’s producers just announced that Glee‘s rendition of Katy Perry’s Teenage Dream debuted at #1 in digital track sales with 214,000 tracks sold, the first time a Glee track has done so. (Glee‘s signature song, cast’s version of Journey’s Don’t Stop Believin’ reached #2 in May 2009.)  The feat is very impressive as the song’s performers don’t include a single member of the core Glee cast. Criss sang the solo literally seconds after his character was introduced on the show as a recurring.
