I'm not sure if this is the correct place to post this, so if not, please put it in the correct spot. I have iTunes on my Dell laptop. When I open it up I can see all of my music listed with a check beside each one. When I click on a song, it says "The song could not be used because the file could not be found. Would you like to find it?" I click on Locate and it takes me to a box where the iTunes are listed as media, library, etc.... but every time I click on one, it puts an exclamation mark by the song and it still won't play. Does anyone have any idea what is wrong, or where are the songs? I have almost 1500 songs and can't listen to any of them. Thanks.
