Steady-state cardio, long efforts.
Most running playlists chase BPM-matched bangers. The albums here go the other way — instrumental, propulsive without being aggressive, designed to hold a steady cadence over a 45-minute easy run rather than spiking your heart rate. Pick a workout-tagged album and let it carry you; pick a focus album for tempo runs where you'd rather think than be hyped up. No lyrics to mess with your breathing pattern.
