Which player are you using to listen to the songs? I'd suggest you try another player to check the problem is LW's media player & not the song files. Unfortunatly LW's media player can have problems if you're very busy downlding. So instead, many people disable it so when they want to launch music, their default audio player opens instead. To do this, go to LW's menu bar, Tools>Options>Player & uncheck option. You may need to close & re-open LW before this takes effect.
