How do I set my music to "Open with" a certain program other than iTunes?

I dont like to use iTunes until I got my music sorted in there...want to use VLC to play songs.

Right-click on a music file and "Get Info". Change the "Open with" app selection, then click "Change All". Done. If you have more than one type, you'll need to do it for each file type, such as one .mp3, one .wav, etc.
