Just 2 things: - "Pls. Short" should be "Pls. Sort" I think that was a typing mistake - If you could make the Right Click Menu's color gray instead of black, because the black menu is not appearing well over the dark background
Really nice looking skin ... however personally my "OCD" goes crazy when I can't resize the player horizontally to make the song-list (right side) wider.
And also note for you next skins: Currently there is a bug when it comes to rating your songs using those stars in AIMP4 beta. They added a neat feature where it stores those stars to the ID tag, however it won't save it if you are trying to rate the song while it's currently playing. So I personally suggest that you let us see those stars in the song-list as well (just like in the default skin).
