Lea Michele's final 'Glee' solo was written by co-star Darren Criss. It's emotional.

It's almost time for Lea Michele's swan song on Glee. That song is going to be an original called This Time.

In the Glee series finale on Friday, Michele performs an original song (as her character Rachel Berry) written by co-star Darren Criss (Blaine Anderson). Criss told EW:
“I wrote ‘This Time’ as a love note to all things 'Glee.' The show itself, the emotions of the people leaving it—both the characters and the actors themselves, the effect it had on everyone — I tried to cram all these ideas into a single person’s narrative. I wanted Rachel’s words to encapsulate not only her own personal journey, but everyone’s experience of being a part of this show.
The song, which you can stream on EW's site, shows off Michele's amazing range, of course. If you're a Gleek, you will FEEL IT.

Criss shared videos of himself writing the song on Twitter:

This isn't the first song the Hedwig and the Angry Inch star has written for Glee. Criss also penned Rise:
