I like using Pandora, it's a great music player that has introduced me to a lot of artists, and songs that I never heard of. But when I use the standard web app, I've always wished it could have a pop-out feature for a mini-player, where I don't have to shuffle through browser tabs to skip a Brittney Spears track that magically found it's way into my hip hop station.
Here's an idea of how it would look using existing design elements...
Adding a button to launch the Pandora mini-player to the existing control bar.
Mini-player stays on top of browser.
Panorda mini-player giving the user the essential features in a more accessible package.
Dropdown menu for list of radio stations.
Collapsing cover flow.
