Backup music from IPOD to PC or Mac

One of the most annoying aspects of the IPOD seems to be the impossibility of back music that was backed up into the IPOD. Now, there is a company that offers a solution, thus allowing people to downstream their music into a different computer. Has anyone tried this software called "Ipod Liberator 2.0" How does it work? What about sound quality?

I have not tried Ipod Liberator 2.0, but i have tried and used Winamp. The current version of winamp allows you to read your Ipod as a fully accessible drive. Just drag and drop in either direction and presto
Wow, is impressive that one of the oldest free MP3 players in the net can do such service. Did you detect any problems with certain tracks or degradation in anyway?
I purchased PodWorks. Haven't used it much, but it seems to work well, has nice features and is easy to use. Don't have any reason to suspect there would be sound quality issues. PodWorks can export iPod music to new folders by artist or album on your hard drive or directly to your iTunes music folder. I got it mainly because I wanted to update my iTunes music library with metadata, namely star ratings, that I created on the iPod itself.
