I guess but don't take my word for it that WMP is a lot heavier to function in a frontend. Because we are not all using high end computers in our car we would like to keep our program light.
Maybe we also use Winamp because it is a lot easier to communicate with it (but this I do not know for sure). I guess controlling winamp and getting information from it is a lot easier then using microsofts one. Also the question is what version of WMP are we going to use.
Also not everyone has internet in his/her car so maybe it is just not interesting to update song titles and stuff over the web.
*** UPDATE (6-11-2007) ***
As for the frontend. The mainmenu is finally working. Still have to do some bug fixing and testing but as for the skinnable part it runs fine. It is now also able to grap information from the framework such as current artist, song, speed, satelites, etc, etc. As for the memory usage (could be interesting) it's 7.5 mb so that isn't much yet compaired to roadrunners 18 mb. Bare in mind that the framework has already loaded sound stuff, video stuff, plugin managers and gps.
Will try to build a simple skin tomorrow and make some screenshots. Just to show how it works. Then I will start building the music plugin.
With kind regards,
