How can I transfer the songs on my iPod to my computer ?

Download Ipod Copy. They give you 30 day demo. It worked well for me.

The quick and dirty way to solve your problem is to browse through the hidden folders on your iPod after mounting it as a hard drive on your system. However, browsing through the folders on the hard drive increases the potential for corrupting the iPod database, which may result in losing all your songs from the iPod before you transfer them to your PC. Use this method at your own risk. Procedure for this is 1) Connect the iPod to your PC. If iTunes starts syncing (ie erasing) your music automatically, hit the X in the upper right hand corner of iTunes display, to the left of the search box, to stop it. 2) In Control Panel, Portable Media Devices, double-click your iPod. In the Tools menu -> Options, in the View Tab, check "Show hidden files and folders." 3) Navigate to the Music folder. On my 5th gen 'pod, the full path is (F:)\iPod_Control\Music Select all the music folders, and drag and drop them into a folder on your hard drive, or directly into iTunes. And you're done! The iPod music folder structure is strange and inexplicable, but once you move your files into iTunes you can set it to automatically organize your folder by artist and album to clean that up. (To do this, in iTunes Edit menu, choose Preferences and in the Advanced tab, check "Keep iTunes Music Folder organized.") Secong method using a third party software: the ability to copy songs from your iPod back on to your Mac or PC is not supported in iTunes, so you will have to depend on the third party utilities.
