D'oh! I'm really good at coming up with non-themers. How about "1984 American coming-of-age comedy film starring Molly Ringwald, Michael Schoeffling, and Anthony Michael Hall." SIXTEEN CANDLES. You're welcome.
Thanks for solving! "19th Nervous Breakdown" doesn't quite work with the PRIME TIME reveal, but it would be a great themer for the reveal PRIME NUMBERS with numbers being songs. I've played around a bit with that idea in the past. Based on length, it'd have to a Sunday grid.
