It's very cool but would like a lyrics feature too! Also I've found as long as you're focused on the Chrome application then you can use the Deezer controls. For example I can't go next / prev song outside of Chrome, maybe you could fix this? Anyway it's excellent and exactly what I was looking for :) But yeah some other suggestions here could be taken into account ;)

It allows users to pause, resume, and navigate through music on Deezer, displaying album covers, track titles, and artist names
The extension offers multiple popup styles, hotkey control, and customizable notification settings
Additionally, it is open source and can be accessed on Bitbucket for code review and modification
