I have a better option. Why not make wmp or other player your default player for LW!? Go to LW's Tools-Options & Player & untick the media player. Press Apply & OK (you may need to wait until next time you restart LW but try if it works immediately anyway.) This way LW's media player will be disabled & your system default player will play them instead when you launch the songs. Good alternatives to wmp are windows version
iTunes & also
QCD (free). Highlight an mp3 go to file-Properties to select a default player/new default if you wish to change it from wmp.
