iTunes question

I've a got a 160GB Apple IPod classic. In addition to loading my songs I want to put my language learning & self improvement audios on there. Is there anyway to get iTunes to separate these from the music list so they dont' start playing while Im listening (like if I'm just playing it from iTunes alphabetical 'songs' list, or 'artists' or 'albums') or will I just have to load all my music onto my own 'music only' list to avoid this??
Also I live with someone who got a 20GB iPod & I hate his music. Will his iPod automatically have a separate library when he plugs it in so we don't have to go through all the checking & unchecking songs?
I ahve disabled autosync.
Thank you.

 

Is it possible to have another iTunes download? We could put one in the external drive & then he would have his own? Would the computer allow this?

 

I would set up two user accounts on the Computer. One for you and one for him. As long as he syncs his iPod logged in on his user account on the computer the music librarys will stay separated without the need of another iTunes install (which isn't really feasible anyways)

As far as separating out your self help books I would do like David suggested and create a Playlist for music and one for Audiobooks and play from those playlists and not your full library.

 

RE: playlists. Yeah that's what i didnt' want to have to do, but oh well. Sometimes I like to play 'albums' or 'artists' so the order of the songs is changed.

We like it when we don't have to screw around with passwords at start up. IT is stupid of iTunes not to let us do multiple users, isn't it? i guess I should go yell at Apple.
