Apparently the next version of LW will have full iTunes support for Windows. If it works the same as Mac osx, then if you select iTunes support in your options of LW, everytime you dwnld an mp3 iTunes will copy it to its own library (which of course will be arranged the way you suggested.) The suggestion of LW dwnlding into particular folders has been suggested many times before & I think later versions of LW will eventually have this.
