Is there a way to unsubribe to iTunes Match? Every software update, it defaults and automatically turns from off to on and wipes out my entire music collection which iCloud is not recognizing because I have a G5 that I cannot upgrade any further. IiTunes

Unsubscribe to ITunes Match. Is this possible?

Since all my information is backed up on my G5, which cannot be upgraded to the current versions of iTunes, software updates default to iTunes Match to an on position which wipes out all my music, and at last update downloaded 3400 photos to my iPod touch from my computer that I couldn't remove until I did a total reset all over again. It took 2 additional tries and 10 hours later to finally get it to load my music back on with the selection of iTunes Match finally turned off manually. This is happening on all my devices, iPod touch and the new iPad.
