Glee has covered hundreds of songs (and created several original tunes) during its first five seasons on the air, but with the sixth and final season set to bow in early 2015, the days of epic covers and millions of downloads will soon come to an end.

Glee co-creator Ryan Murphy has said that he knows exactly how he wants the show's final season to go, and his vision may or may not include song choices, as well. But if he needs help deciding what tracks to tackle, Lea Michele (Rachel) will be ready to chime in with suggestions of her own. But of course!

Lea was a guest (alongside the legendary Debbie Harry) on Watch What Happens Live on May 22, and she opened up about her favorite songs she has covered recently, as well as one older track she'd love to take on in the final season. "I got to sing one of my favorite songs this season, which was 'Glitter in The Air' by Pink, but now I have one song… I've always wanted to do 'Teenage Wasteland (Baba O'Riley)' by The Who. That will definitely have to happen next year," she dished.

So does Lea have an ideal track for Glee's last song ever in mind? You bet!

"I always think about what I would want the last song [I sing on Glee] to be. That's my biggest thing," she confessed to Andy, later adding, "There's one song that I think it has to be, so I'll keep it on the… Yeah, we'll see."

We get why Lea's opting to keep her pick for the series' final song a secret, but we do wish she'd given us a little hint about her chosen track. Oh well, looks like we'll just have to start speculating below!

What do you think the last song on Glee should be? Check out the full video with Lea and tell us your thoughts in the comments!

Glee Season 6 is expected to debut in 2015.
