Spotify Profiles +
I'm not a UI designer by any means, but thought I'd tag onto the rebound train of Ramotion's project with a stab at improving the profile section of the Spotify desktop application. Just because. :D Some key ideas/implementations:
1) The ability for a user to control their profile image, and to write a bio.
2) A bit more user control over what appears on the user's homepage. You could select specific artists or even playlists to be "Featured" to help personalized your page and show off your tastes.
3) All playlist creation and organization would be moved from the cramped domain of the application's sidebar where it currently lives, and would now be accessed and controlled via drag & drop on the user's homepage. As always, only playlists that are public would be visible to everyone. Also: custom playlist cover art, while I'm dreaming.
It's not perfect of course, just a concept!
