i just use samurize for winamp now, it runs decently, and i can config it to my liking, plus the only thing i really need thats actually part of the WA gui is the playlist ;) you can see what the hell im talking about in my recent SS: XE
I'm not a winamp fan, but I tried a Samurize config for iTunes and it was a bitch. I eventually dumped it because I could never figure it out unto my liking, shit....if anyone can do that I applaud them.
pm me, i'll send you a basic winamp currently playing config you can mod to your hearts content. It's extremely easy, and to control winamp with rainmeter is easy also. Dont go by some peoples skins on here that use rainmeter to execute an app to control winamp. It can do it itself.
