Probably don't want to be this generic... iTunes is organized as:

Root/iTunes/library.xml
Root/iTunes/Artwork
Root/iTunes/iTunes Media/
Root/iTunes/iTunes Media/Automatically Added to iTunes/
Root/iTunes/iTunes Media/Music/{Artist}/{Album}/{Songs}

Probably Root/iTunes, Root/iTunes/iTunes Media/, and Root/iTunes/iTunes
Media/Music/ should be treated as the same as the XML file, but not other
things. Just the Album art could be different, a specific artists could be
different...

Haven't looked at iPhoto
