I debated between this and Lucius' equally propulsive "Don't Just Sit There" (both of which are regulars on my longform running playlist). I went with "How Loud Your Heart Gets" because mine does get pretty loud, especially while running. Also, remember: "The things we know, we just don't know."
Can't wait for the new album to drop in March! In the meantime, I'll listen to their Tiny Desk concert at least once a week.
