You can listen to any track on repeat. Simply go to the player on the bottom of your screen and click on the arrow icon:
Clicking on the icon and turning it orange will activate ‘repeat’. The song will repeat until you uncheck the icon. You can also press ‘SHIFT + L’ on your computer’s keyboard to turn the repeat button on.
Please note: At this time, there is no repeat feature available on the mobile site. The iOS app has a repeat track function. The Android app has both repeat track and playlist via the Next Up feature.
