iTunes Match, adding existing songs to libary
Hi All,
Ok, I have most of my music matched/uploaded to iTunes match. I've backed up all the music to an external hard drive and wiped my itunes folder clean. Now on my external hard drive I have a mix of the songs matched/uploaded iTunes match and also new music I've not imported into itunes yet.
Does anyone know if I copy all the music back into the iTunes folder and then add the complete libary back to iTunes will match recgnoise the already matched songs or will I end up with a bunch of duplicates? In total approx 8,000 songs of which 6,500 have been previously added to ITunes match.
Thanks in advance for you help.
