How can I download my content from Mac Formatted iPod to PC?

I am a songwriter, and record my songs, live or otherwise onto my Ipod via Alesis Pro Audio Equipment.

I own an older Ipod, but it still works beautifully, and integrates with my Alesis recording software.

I have thousands of hours of live shows, original songs, all mixed in with MP3's from my ex's old iTunes account, (I paid for all of the itunes items myself).

PROBLEM: Went to a bass players house when the iPod was new, and hooked up to his Mac computer in order to add his recorded bass tracks onto the iPod.

Now, months later, I decided to dump all of the recordings and organize them onto my PC, and when I plug the iPod in, it says "REFORMAT DEVICE?"

NOOOOOOOO!!!!

Other than buying a Mac, are there any other options I have that are EASY to do, in order to salvage my recordings, and the itunes songs purchased?

I need my music on my PC, and I need more space in my iPod!
