Bumping my own thread, two songs with phone numbers.
867-5309 / Jenny by Tommy Tutone
and
777-9311 by Morris Day And The Time
Since the first title contains minus and divide signs, I felt a closer mathematical inspection was warranted. It revealed not only that
8675309 is a prime number but so is its
twin prime 8675311 perhaps is it Jenny's twin phone number (though she never got her own song).
Interestingly, the second title
7779311 is also a prime, which could cast doubts of plagiarism would it not be for its vastly different style and incredibly unique hi-hat beat.

Oh, and there is more to it. Somebody has expressed 8675309 as
(7⁽ᵉ⁻⅟ᵉ⁾ - 9) ∙ π² ...also revealing the year the song was written!
