I delete songs off my iPod but iTunes reuploads them

Hi,

I have an ipod touch 4g. I'm always finding new music and updating my ipod. Oftentimes I'll be listening to a new album (on the go), and not like a song, so I delete it from my ipod (but don't bother to delete it later from my iTunes library). Next time I go to sync from my iTunes library, however, iTunes re-uploads all the songs I'd deleted from my iPod. I find this tremendously frustrating. Is there a way to tell iTunes NOT to do this?

I feel like this is a really stupid question, my apologies. But I've done a search in these forums, and tried to figure out how I might do this in iTunes, but to no avail....

Anyone have any tips on this????

Thanks!

Uncheck the songs you do not want to reload in iTunes.

Make sure in iTunes Preferences/Devices you have checked "Prevent iPods, iPhones and iPads from syncing automatically and as osxx posted above uncheck the songs before you sync your device..
