You can associate your music files with any player, I use QCD and do it like this..
In explorer, navigate to one of your files and right click it.
It will then give you the choice to 'Open With', click that option.
Now you will be given a list of all the programs that are on your PC. Select the player of your choice and tick the box to 'always open files of this kind with this application' (or words to that effect).
You can tick the box in LW to play songs in there, but you have to change the option and then close and relaunch LW for the changes to take efffect.
'Open With' works with any file, I did it with graphics files, making them open in my browser so that another application doesn't need to be launched
