My other half bought me an IPod nano (in pink lol) for my birthday and I have been trying from yesterday morning to get music on it!!!!

I can get proper CD's on it but I have an external hard drive that has over 500 albums that have been downloaded from limewire or torrents and I would love to copy a few off them across to the IPod. The problem is they go into ITunes ok but they go in as single songs and not as the albums I have created and they mix up with the CD albums I have already ripped.
The instruction booket is

PLEASE HELP!!!!!!!!!!!!!!!!!!!
