Then I guess you'll have to either drag and drop the mp3 (try it to see if it works) or double click them (if you see them as iTunes files).
Dunno how you do it in a 9.2 OS, but you'll have to define iTunes as the default application for mp3 in order for the later to work (in OSX, if you ctrl-click an mp3 file then click Get Info from the drop down menu, you can change the default application by going to the Open With options)
