I have settled on ICEł as my main media front end. It, like most other Mac front ends, is not currently under development
ICEł home on MP3Car.com is here.
There you will find discussions about it and custom themes.
So after I downloaded ICEł and played around with it I went looking for more info on it.
I ended up on the ICEł website.
There I downloaded all the Themes, HUDs & Visualizers I liked, and played with all the settings. Here is the theme I like the best.
It's called "Vented" made by one of the developers, Steven Ramsay.
After I found the "Use iTunes Music Library" option, I was rocking out ICEł on my 15" MacBook Pro. It looked funny running in the corner of my screen while still seeing all my other windows behind it, so I changed my screen resolution to 800x600 to help out a little.
The second page of the "Settings" has four greyed out options that are not implemented yet. They are KEYBOARD, APPLE REMOTE, Wii REMOTE, GPS, XM RADIO and OBD. At first it didn't really matter to me that they had never implemented these features yet. Now after going futher down the carpc rabbit hole, I REALLY wish the KEYBOARD, GPS & OBD were integrated! (So does VmtSquad, see his thread about trying to get the source code here).
Deeper in to the rabbit hole with ICEł, still to come...
