missing music

I recently traded in my iMac on a MacBook Pro. Using Time Machine, I transferred files from my old system to the new one. Some of my music on iTunes now says "original file not found" and won't play. Some of the music can be replaced because I have the CDs. Some of the music is only on my iPod, however... is there a way to transfer music from my iPod to my MacBook Pro?

Try this application. LINK Note, however, it's not free. There are also other apps which can transfer music from your iPod to your Mac, so do a Google search. I'm not sure if any of them are free though.
