Title should say, "How to open iTunes from the terminal in OS X".
Don't be mean. The clever part is the calling of the fuzzy-selector utility. (I guess you pick an artist or track, type as much it as you can be bothered to, and it will play the track or, if it's ambiguous, offer a list that narrows down as you type more).
He is right. This just launches the default player. I just got excited about the selecta utility. It is a great tool for replacing graphical user interfaces, since many GUIs can be boiled down to fuzzy finding. I live in the terminal, and I think I am actually going to use this script to launch my music from now on.
