keep in mind that downloading music from whatever source wether it be LW or even a pay service like napster is like picking thru a giant trash pile . your going to find lots of songs,videos,software that wont work or is corrupted. try re-downloading the songs . or you might just need CODECs (short for coder-decoder) . moast of the basic ones are allredy on your computer but if for some strange reson there not , get the nimo codec pack . google for it. (moast likley tho the songs are just corrupted/broken).
