"I plan buying a new computer soon and I know it's gonna not let me put my songs on to it you know the whole 'it looks to me like your stealing music' deal"
Actually you can put songs on, you just need to set the iPod to manual update on your current PC before connecting to the new one. When it is set to manual you can connect and use your iPod without the risk of accidentally erasing it:

Managing Your Songs Manually
You can't sync or drag your music back directly from an iPod to iTunes, the transfer of music is designed by default to be one way from iTunes to iPod. However there is a manual method of accessing the iPod's hard drive and copying songs but not playlists back to iTunes on Windows posted in this thread:

If you prefer something more automated then there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod, this is just a selection. Have a look at the web pages and documentation for these, they are generally quite straightforward.

YamiPod Mac and Windows Versions

Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync again.
