What Are the Most Popular Workout Songs?

— -- When you hear the perfect workout song, you know it.

As your feet hit the pavement in time with the beat, the song makes you feel kind of like a dog sticking its head out the window of a moving car -- even though it’s 85 degrees out and you still have three more miles to go on your long run.

It’s that good.

Billboard teamed up with Spotify and Echo Nest to study Spotify’s more than 40 million users’ most listened-to workout songs. They crunched the numbers on the most popular genres and artists, and put out a playlist for every activity, from running to yoga to Tae Bo.

Eminem’s “’Til I Collapse” was the top song across all categories, propelling him to top artist. (Though, not surprisingly, he’s nowhere to be found on the yoga playlist.) Skrillex and Macklemore with Ryan Lewis took second and third place, respectively.

Most people preferred to listen to rap and hip hop, but genres varied across activities. For instance, joggers preferred to listen to pop and alternative songs, while people who did CrossFit were more into rock and hip hop and rap.

The yoga crowd preferred new age and ambient music.
