We have introduced both a 3-8 second looping visual layer for mobile devices, called Canvas as well as videos for some songs. However, these features have not yet been fully rolled out and availability can vary from user to user. If you want to find out more about the features we are testing and implementing, you should visit this support page.
You should also make sure you have Canvases activated in your settings:
Android: Home > Settings > Canvas
iOS: Home > Settings > Playback > Canvas
Hope you find this useful. Keep us posted if you have any questions.
Have a great day!
