Where can I find all this Ghibli music?
eBay - cheapest finds here but choice is a bit limited
amazon.jp - more pricey but because it’s direct from Japan it means you can find almost anything
Yes Asia - nice extensive catalog for anything from the Far East
iTunes store - search “Ghibli” and lots of whole albums should be available for download
FFShrine - search the forum for lots of download links
Hope that helps!
