HELPPPPPP Cant locate songs on itunes

Hola newschoolers.

I recently got a new laptop and was switching over my music from ipod to computer, everything went fine, all my music played until...........the next day.

Now when ever i want to play a song this message comes up.

"The song "Fortunate Sun" cannot be used because the original song could not be found" then it asks if you want to locate it and i click it but it doesnt do shit.

I've searched the internet but none of the advice makes sense to me. My songs arent saved in their titled form. They're all "FGKZ" GJFV" and shit.

I tried reinstalling but that didnt work.


So I come to you gents for help.
