i am new to lw and i downloaded some songs that said mp3 and they played as soon as i got them then i saved them in my playlist and now they wont play except for 3. they r in my saved file and in red and wont let me share them i tried right clicking share files but doesnt work also tried it in tools. if they r corrupted files how do i get rid of them as they say file somewhere else can not delete. thanks
