What music gets you through the hardest intervals?

I find that the right playlist can make or break a hard interval session. I’m always looking for new music that keeps me pushing when the legs are screaming. What do you listen to during your toughest workouts? Any go-to artists or playlists that never fail you?

So many of the Sufferfest workouts have it just right. I am thinking Team Scream, The Chores, Recharger.

Right now I am doing some work and have a Spotify playlist running, called The Sufferfest: EVERYTHING. It was put together by a certain David McQuillen.
