Don't get me wrong, I love the layout, and the look of it. The album covers in the library are a nice touch as it makes finding your music by sight a lot easier. The downside is that they take up a lot of room so you do a LOT of scrolling. I quick link list at the left side, like in WMP10, would be good.... But it just isn't as customizable as it could/should be.

And it is available for XP - you don't have to have Vista for it...
