Go to LW's menu Tools>Options>Player & Untick Player option box. This will mean when you launch a song, your default mp3 player will play instead. A decent player is QCD (Quintessential Player: a free player with built-in codecs that plays all mp3 types) Outside of LW select an mp3 & go to File>Properties & select 'Open with ...' & select QCD to always play it.
