i play a song and its says not found why?

Hi vjoffroad3,

When tracks in iTunes display a it means the file cannot be located; it may have been moved or deleted. For this issue, see the following article:

Alternatively, if your media was downloaded from the iTunes Store, you may be able to download it again free of charge:

Thanks,
