I'd like something that combines the features of the rdio interface with the music stored on the device. You could have the option of having the app automatically detect all the music on your device and add it to "My Collection" on rdio. When you make a playlist on your device, it creates the same playlist on your rdio account, and when you make a playlist on rdio, it makes a copy on your device if you have the majority of the songs stored. the idea is that you have access to pretty much the same library and playlists whether you're using your device where there's no internet, or when you're using another device (library computer, temporary phone, etc) and your own device isn't around. I have a tablet with wifi at home, but I have no internet access when I'm in the car, it would be nice if I didn't have to make all my playlists twice.
