I have to say at the onset I don't use WMP and haven't done so for some years.
I would recommend one or two music programmes I personally use. I suggest you try the free version of Winamp or RealPlayer and import all your tracks into them. (I have the full 'paid-for' versions of both as music is my main hobby.) That way you can create your own playlists using 'drag and drop' and save them for future playing. They both take a bit of getting used to, but that aside, I feel both are far superior than Windows Media Player.
I suggest you try Winamp first though as its the one I use most.
Hope it helps.
