Speedy Ortiz recently announced tour dates, and today they’re sharing a new track titled “Bigger Party.” Hear it over at the A.V. Club, or stream it below. And you might remember this song in demo form from our Marathon Relief Mixtape.

The song features a pretty catchy chorus from Sadie Dupuis: “I’m really sorry for the time that I made out with all your friends / I’m really a shithead.” But it ends with the perfect kiss-off: “I’m not that sorry.”

The song is released as part of the Adult Swim’s single series, and it’ll be downloadable starting Monday.
