Currently the default application for mp3 files on my Macbook Pro (10.6.8) is iTunes. I want to change it to QuickTime. So I right click on an mp3 file, select Other, check the Always open with box, scroll down to QuickTime select it, then click Open. The mp3 file plays with QuickTime. Bueno.

However, when I click another mp3 file, it plays with ITunes. I want all mp3 files to always play with QuickTime. How do I do this?
