Starring Stranger Thing‘s star Shannon Purser, who played Barb in the sci-fi series, is not only star in the upcoming film, she’ll also be lending her voice to one of the soundtrack’s songs.

Both the film and the soundtrack is set to be released on Sept. 7, and ahead of its release, Billboard has unveiled the movie’s official tracklist.

The soundtrack has some pretty big names on it, including jams from Sabrina Carpenter, Betty Who, MNEK and Allie X.

Plus, judging from the tracklist, Purser will be singing a song that was co-written by Troye Sivan called “Sunflower,” and we imagine it’ll play an important part in the film if the star is singing it!

But that’s not the only songs Troye has helped pen on the album.

In total, Sivan has co-written three songs on the upcoming soundtrack: “Sunflower,” which is sung by Purser, “Kid Wonder” (MNEK) and “The Other Side” (Betty Who).

We’re beyond excited to hear the new songs, and we’re even more excited to see how they’ll fit into the new Netflix movie.
