Unfortunately, that's what I mean. It's not as simple as copy pasta for skinning. I've had numerous errors where the skins just didn't skin certain aspects of the player and errored endlessly. It is the most difficult media player to skin hands down. Winamp is easier, Media Monkey is easier, songbird is easier..
I personally use Media Monkey and that is a great player. SongBird I don't like because of the audio quality. It just sounds inferior as odd as that sounds.
Winamp was great and as far as audio quality goes is right next to Media Monkey. I used Winamp for the longest, but gave it up for MediaMonkey. I used the Bento theme for Winamp and now that I'm on Media monkey I use this slick black theme.
To the poster above that was talking about itunes, I think as far as functionality is concerned, itunes is great. It's simple, straight to the point etc...but it doesn't support FLAC and that shuts it down hard. Consider Songbird if you want a very similar player that does play FLAC.
