We previously reported that the new season of HBO's "Girls" would feature a new song from St. Vincent called "Teenage Talk". The song closed out this week's episode—and while it hasn't been officially released, a ripped version surfaced on Tumblr. Check it out above. Update: The full, official stream of the track is now available above via Spotify.

St. Vincent isn't the only musician to record a song for this season of "Girls". Grimes collaborated with Jack Antonoff of fun. and Bleachers (who is also dating "Girls" star/creator Lena Dunham) on her new song "Entropy", which will play during a party scene in another episode.
