Is there a way to associate file types with a program?

[John Moore]

Hey all. I am trying to get .ogg files to associate with ITunes  
because I am sick and tired of having to vo+shift+m every time, go  
down to Always Open With, choose Other, then choose ITunes. Is there a  
way I can get the Mac to associate .ogg files with ITunes? I really  
hope there is. Thanks for the help.
