Not crazy about it, sorry. The background grey seems too light, when in thumbnail view, my album covers are not as vibrant as they are using another dark skin such as Blue Steel.
The drop-down/pull-down menu's bevels are distracting, hard to read the text, just looks a little sloppy, gawky, klutzy. I'm also not too crazy about the centered menu, but I don't know why, probably because I'm not used to it.
Really not crazy about the beveled selection in the tree menu, way too much of a separation between the selected and not selected (which may actually be sub values of the selected) and the highlight is too bright.
It is a little hard to tell that the speaker icon by the volume slider is a speaker icon.
Overall a bit too busy and makes the software look more complicated than it is...
Hate to seem so negative, hopefully I've been specific enough to show where I'm coming from. Good news, seems I'm in the minority!
