iTunes not allowing copying music

[thefireboy]

Trying to copy some songs from a USB Stick an iMac, they'll copy to the computer however when i try and add them to the iTunes library an error message comes up and says something along the lines of ' you cannot copy these files to 'HDD' due to insufficient Privileges'
How can I get it to work
cheers

Have you tried Checking Permissions using the Disk Utility program in your Utilities folder?

 

[thefireboy]

Permissions verified then repaired. Verifying disk now
Edit: Verifying disk because repairing permissions didnt fix it

Disk needs repairing, thanks
