Pop Poll: What Britney Songs Should Be on Glee?

It seems like Glee rumours are a dime a dozen these days, but here's one dream that's becoming a reality: creator Ryan Murphy confirmed that season two will include an episode featuring the music of Britney Spears. There's no word yet on whether or not Spears herself will get in on the fun, (you know I would love to see her on the show), but I'm already brainstorming what tunes the show should choose. I'd love to see Rachel channeling her inner bad girl on a song like "I'm a Slave 4 U" or "Toxic," though we're probably more likely to see her belt out "Lucky." Dianna Agron seems to have a voice that's perfect for Spears's pop melodies, so I'm sure Quinn will get in on the action, too. Which songs will you be hoping for—and better yet, who should get to sing what?
