# songs that start with the word I, and not I'll or I'm, which would make the list even LONGER!
# that I know; there's a couple other titles that sounded familiar, but eh
# that went to number 1 on the US Billboard pop charts
# that came out before 1992, because my Billboard Book of Number One Hits ends there
