Whooooo, look at AROSAmp! Mithrandir has been doing some fancy work and developing alpha version 2.0 of AROSAmp. He commented on the screenshot he posted and he describes it nicely. The post follows:

"AROSAmp Alpha 0.20 will be including full support for skinning.
The skinning system allows for (almost) unlimited freedom in skin design.
Make your own skin entirely from scratch, or simply remake the skin your preferred mp3 player has today!

As you can see, the skinning is still lacking ID3 font support, and controls for volume, and balance.
However, the MP3 player is coming along nicely.
It shouldn't be too long before it is all done. All buttons shown on screen is working, and counter is working perfectly.

Hope you enjoy the screens of the player in development,
I'll see you all as the release comes closer!"
