It takes a lot of time and energy to search for and download music for your workout. What you typically listen to throughout the day may not be what keeps you moving at the gym. Other streaming music apps give you one song at a time and have no control over BPMs (beats per minute) – Pandora, for example, will give you a fast, upbeat song but it will be followed by a slow, drawn out song that in no way matches the rhythm of the song you just previously heard. Spotify is just like iTunes, it lets you decide what you want to hear. However, flipping through songs can be very distracting when you’re trying to reach your goal of a seven-minute mile.
