Anyone who watched the first season of Glee would be more than familiar with their choir-tastic rendition of 'Don't Stop Believing' by Journey.
In fact, it was one of the highlights of the cast's set during their live tour this year.
But even legit rock n' roll fans get sick of hearing uplifting anthems night after night. Just ask Glee's own Cory Monteith!
The 29-year-old actor, who plays Finn on the hit show, was asked whether he'd tired of any of the show's cover versions during his time as a Gleek.
"I've heard 'Don't Stop Believing' a few times," he told TheFIX.
"I'm just gonna come out and say that - I've heard it once or twice!"
Co-star Heather Morris was quick to defend the song.
"I like the real version, a lot!" she said.
"I like every music thing that happens to the world, even if we take a break [from Glee] I'll listen to a song after about a year and remember I love it."
Glee: The Concert Movie is out on Blu-ray, 3D Blu-ray and DVD now.
