Is this crash normal?

My Snow Leopard crashed while I was switching from Itunes to the browser.

Basically everything got stuck and a the current song second started to run in loop.

Is that normal ? Can it happen very rarely ? Or should I worry ?

thanks

You should worry if it happens to you periodically. If it happened only once, my guess is one of the background process Mac OS X runs from time to time got stuck for a moment.

BTW, when you say "crash", did you have to reboot your computer? Or did it just got stuck for a period of time?

Anyway, if it crashed, the best you could do is send the crash report to Apple when prompted and check the Usual Suspects:

• Background processes => System Preferences > Account > Login Items (remove the one you don't need.
• Check how much free space you have left and start removing the files you don't need
• Maybe try to reindex your hard drive
