On September 5, Glee released five brand new songs from the upcoming Season 4 — and these are definitely some tunes you won't want to miss. From Blaine (Darren Criss) and Artie (Kevin McHale) singing Justin Bieber to Brittany (Heather Morris) simply killing it with an awesome version of Britney Spears' "Gimme More," we think it'd be pretty much impossible to pick a favorite from these five tunes.
