Hey Tristan,

Firstly, we love feedback so please don't hesitate to provide it! Thank you.

The green dot means the track has successfully uploaded and should be streamable or downloadable on other devices.

The pink dot means the track is downloaded (on a secondary device) and the same goes for the pink dot next to a playlist.

A greyed out track mean it's missing. Either deleted or moved from its original imported location.

Ready... means it's all up to date or the stage has not begun. There is a temperamental issue where sometimes it gets stuck on Preparing.. but for future reference you should be able to reload or quit and restart the app to fix it. We're still trying to track down the culprit on that one!

I hope this info helps. Please do let me know if you have any further questions at any point.

Remko
