I just found this app, and I love it!

Bowtie is a free application that allows you to control iTunes and your iPhone (requires 99¢ companion app) with customizable shortcuts, submits your songs to Last.fm with support for Loving and Banning, and sports a very simple, yet very powerful, html5 + css + javascript based theming system.
