Fixing up your iPod music collection

Found this cool video which explains how to get rid of duplicate entries, adding artwork, tags.
I found this very useful as I am new to iPod.

Video can be found at Cnet Reviews.

Stumbled upon this cool video explains the concept behind binary addition (same as what the computer uses to compute), in this video the Mathias Wandel uses a wooden machine and using marble explains the concept.

Watch the video
