MacBook Air closing down

How can I prevent my MacBook Air from closing down by itself when I am offline and just listening to iTunes.

Can you explain what you mean by "closing down"? What exactly is happening.

MacBook closing down

When I am offline for a while, my MacBook Air keeps logging me out, even when I am listening to iTunes.

Why does my MacBook Air recently want to close down, log out, when I am not online, even when I am listening to iTunes?

Thank you.

Go to System Preferences, Energy Saver and set the Computer Sleep to Never. You can leave the Display Sleep wherever you want. When you start listening and not typing or doing anything on the MBA, the timer will eventually darken the screen but the music will continue to play.

Since the computer cannot log you out when you have any activity running (such as iTunes playing), what's probably happening is that the user has a security setting set to automatically log out the user after X minutes of inactivity, or perhaps has the screensaver/energy saver set to darken the screen after x minutes (perfectly normal) and require a password to bring the screen back (a choice available in the security settings). As Jake says, if the music is continuing to play, you're not logged out.
