Mint Music is a collection of beautifully crafted music widgets using Zooper as the engine and Media Utilities to pull it all together. Make sure you have both of those apps installed before installing. In Media Utilities settings make sure that "Send Song Progress" is ticked.
I gave it the Beta tag because this skin relies heavily on the latest beta version of Media Utilities App. Also because it comes with only three to begin with, I'll be adding more based on requests and feedback from YOU.
