I recently tried to transfer my entire collection of songs and videos from my iMac to my external RAID. The transfer was successful... except for everything I bought from iTunes and some recent additions to my library. I have no idea why 90% of library transferred and the 10% of all new stuff did not, but its gone off my hard drive as I deleted it from the iMac assuming it all went safely to the raid. Anyway... a lot of it I can re-rip... but what about all my purchases from iTunes Store... videos, songs, albums, etc. Is there anyway to re-download them without being charged again?
