It is cool to have the tipical option to share music as Instagram Stories, I use this very much in all the streaming services I had. But Deezer shows by far the ugliest visualization, with just a bright random color in the back. 

Its very far away from other competitors like Tidal, wich I also have, so I always prefer doing this with other services than Deezer. Maybe just adding something better for the background of this way to share.

This shouldnt be complicated to fix, and I think it could help promoting Deezer if people use it to share music on Instagram.

I add images from the visualizations from Deezer and Tidal, so people can know what I mean.
