Oh what a night

If I could only listen to one song for the rest of my life, it would be "December 1963 (Oh What a Night)" by Frankie Valli and The Four Seasons (that link will autoplay, BTW). The lyrics are completely irrelevant (a guy losing his virginity with a woman he doesn't know); I just love the sound of it and it always makes me happy. It's been my go-to feel-good song forever.

My mom used to store all her old records in my closet when I was a kid and she'd been a huge Frankie Valli fan. Before I had many records of my own, I used to play hers. I guess I must have I played that song a lot because it's just stuck with me.

So... One song forever. What would yours be?
