4. Glee Lives and Dies by its Guest Stars and Track Lists
As if it's not hard enough to keep track of the relationships and roles of Glee's fifteen series regulars, there's a constantly revolving door of guest stars. Season one featured cameos by Neil Patrick Harris, Kristin Chenoweth, Olivia Newton-John, Josh Groban, Eve, and a host of other Broadway celebrities in roles both major and minor. Already on the roster for season two there's Britney Spears, John Stamos, Javier Bardem, Carol Burnett, and Meatloaf. It's no secret that announcing big-named guest stars generates big amounts of press (more about that here), so expect the star wattage to keep growing.
Similarly, by leaking track lists and songs that New Directions will cover in upcoming episodes, Glee has managed to keep itself in the headlines on a nearly perpetual basis. Season one featured the aforementioned tributes to Madonna and Lady Gaga, and the upcoming season has already announced similar theme nights around Britney Spears and The Rocky Horror Picture Show. By releasing the names last week of the songs that will be covered in the season premiere, the show has only increased its substantial buzz leading up to Tuesday night.
