I respect everyone's way of doing things, but by comparison, using registrations, one button press brings up the song all ready to go. This does require one to have a set list prepared or have the registration numbers grouped on a list in the manner you desire. I should mention that if and when the search engine is expanded to registrations, a quick partial search of the song name will do the same as a number.

Just a viable alternative
