Can any writers help me out?

[19 cats and counting]

I'm about to submit my first freelance writing piece and I'm 99% done/edited with it.

Question is about puns.  In one sentence I mention an album title and then in the next sentence I mention a song title (as part of the sentence).  Should I put the song title in quotes or just let it slide and see if people notice.

(The album is a very popular one and the song is a hit single, so it's nothing obscure).

AP style says to put the song title on quotation marks.

Maybe this will help
