Random playlists on my iPod?

Hi,

I have a 4GB iPod Nano. Obviously I have more than 4GB of music on iTunes.

Now, when I try to sync, as I have too much data, iTunes tells me it will select its own generated playlist, and sync that with my nano.

Fine. However it selects songs from my entire library. I only want it to generate a playlist from a few of my own playlists.

Also, its own generated playlist never changes. I would like the music on my nano to change randomly on a regular basis.


So, in a nutshell, how do I get iTunes to create regularly changing random playlists based on some of my own playlists - so that I can sync it with my nano?

 

Bump - little help?

 

Anyone?
