My iPod memory is locked and I cant access my songs in the iTunes

You can't play songs from your Ipod, via Itunes, if you've got auto sync switched on.
Right-click on the Ipod in Itunes. Go to options, and select "Manually manage songs".
Of course this does what it says. You will manually now have to add any new songs onto the Ipod.
Enjoy!

Hi there and welcome to iPodlounge.

Basically, it would appear that your iPod is set to synchronize automatically. This isn't really a problem per se, but it does mean that you can't access the content of your iPod directly.

In automatic synchronization mode, any changes you make to your music library in iTunes will be automatically synchronized to your iPod, so you don't actually edit the content of your iPod directly, but rather make the changes in your main iTunes library. In this configuration, your iPod becomes a complete mirror of the iTunes library on your computer. Many people find this to be the easiest solution for keeping their music organized.

However, since it appears from what you're saying that your husband has been using manual mode, and you're both sharing the same computer, you may want to set your into manual mode as well. To do this, make sure your iPod is connected, and simply go to Edit->Preferences->iPod and choose the option that says "Manually manage my songs and playlists" and click OK. Once you do this you should be able to manage the content on your iPod directly.

There are some very good how-to articles on this forum, under the iPod 101/201 series. You can find them by clicking the "Articles" link at the top of the page. I'd suggest reading through all of the ones that interest you and it should get you up to speed on all the really neat things you can do with your iPod.
