The music player from CyanogenMod 9 has been let loose for anyone to download. The app comes with heavy customization so you can personalize it as much as you wish.
There is a theme engine which allows anyone to make themes for the app, enabling devs to customize nearly every single thing you can think of.
The app also comes with some sweet shake and flip actions. You can quickly play and pause your music by simply flipping the phone - meaning you can lay it face down on a table to pause, pick it back up to start playing again. The flip and shake actions stay on in the background so whatever you are doing, you can still use them.
The app should become available in the market very soon for easy download. But if you can't wait to get hold of it, you can download it now.
Sorry guys, completely forgot to mention that you will need ICS on your phone for this to work!
