I have iTunes 6.0.4 running on my eMac with 10.3.9. With my hardware, this is the latest OS I can run. Trouble is, I can no longer buy most songs from iTunes Store because it indicates I need at least iTunes 7.2 or later. I am afraid to download a later version because I am afraid I may lose my iTunes library or cause a crash. But, here I sit with about $50 of iTunes cards.

Any ideas?
