"Not possible using ITunes' any version" you need some Itunes kind of software without restriction.
a lots of people search for copying data from iphone/ipod touch. so here is the solution.
a lot of good softwares are on net.
but some of the best one are following.
1. www.mediamonkey.com - I am personally using it for my Iphone. really cool- as i sync it with multiple machines, My office and Home.
it is very good free software to use. You can sync and copy songs without Itnues.
both free and paid version exist. but free one is cool as paid does not contain enough options to buy it.
2. www.getsharepod.com/ - gave some problem on 2.2 firmware. so did't used.
it is also good.
just google above software you will reach the site and read the details.
now download the software,transfer copy music from ipod to computer|laptop.
Enjoy and thanks the devlopers of the software.
