Do you ever wax poetic about slogging up a hill at 5 A.M., sweaty and exhausted, but held together by the camaraderie that comes with chanting cadences during a unit run? Well, thanks to Spotify, you can now listen to military cadences anytime you work out. Recorded straight from drill sergeants or drill instructors themselves, these playlists are guaranteed to get you amped. The popular music streaming app has cadences from all the services branches, even some that specific to infantry, rangers, or SEALs.
