Spotify Running was introduced a couple months ago for iOS users. Now, Android users will get to use the feature as well. This section allows the app to create running playlists based on how you’re moving. To access it in the app, you need to head to the menu screen and select the Running option. From there you pick a playlist and start moving. The app will detect your tempo and base the songs it plays on your speed.
