Default Enhanced Spotify Management

The stock media remote app seems to work fine with Spotify playing on the phone, however it would be pretty cool to see a spotify-specific app, maybe with the following features:

- like track
- albumart
- track/album name
- playlist selection

There are a few remote apps on the play store, but they are PC to phone, an existing phone to phone one may work, if one exists?

Any one have any idea's if the above is possible? :P
