Exactly what I was looking for: a table listing songs that start with different ascending and descending intervals!

The three that I'd been using - perfect 4th: Auld Lang Syne, perfect 5th: Star Wars, and major 6th: NBC jingle - were helpful only for ascending and only for those three.

Thanks, Footprints, whoever you are.

OR! You can make your own!

Rumba - quickness in getting to chords.

Passacaille - More speed in more sections
