iTunes problem...

So today I opened iTunes and it asked me if I wanted to upgrade to the new version so I did then when I opened it after the upgrade it tells me I need OS X 10.4.7, and I dont really want to spend my time downloading the 64mb file because my internet is slow. So is there any way to downgrade my iTunes back to my old version so I can still listen to music until I get around to upgrading my OS? Also my computer is an iBook G4 if that matters. Thanks in advance if anoyne can help me.

you could always go to the library and download the upgrades onto a flash drive and then install it from there. or you could just pirate someones signal for the 10 minutes it would take to download
