Right now, my MP3s are associated with iTunes as the default application. I would like to set that to QuickTime, i.e. when I double-click an MP3, it'll play in a QuickTime window instead of the iTunes. Could someone tell me how to go about doing this?
Select an MP3 file
Go to File -> Get Info
Expand the "Open with" section
Select "QuickTime Player" from the drop-down menu
Push the "Change All" button
