I know the issue is resolved, as far as the OP has already made his decision, but I’ll jump in, with qualification, on the anti-TS side. As I think about it, maybe not so much “anti” as “teaching moment” side. I think TS songs are unrealistic about relationships in the real world - - I know, that describes most music, and it’s not supposed to be a documentary. Still - - marry me, you’ll never have to be alone? Not a real good understanding of Catholic thought on marriage. Sneaking out to see the ‘boyfriend’? Is this behavior you want emulated?
So, maybe those are the times to ask about your child’s understanding of marriage, dating, courtship, in an age-appropriate way, while enjoying the tunes.
Now, to be fair, I like traditional folk Irish and Scottish music, and one song all our gang (6,5,3 and 4 months) has been singing is “All for me grog”, so you may hear mine singing “all for me beer and tobacco”, but we do discuss how one should never smoke, it will make you sick, etc., and neither I nor my bride drink (or smoke), so I am less worried about glamorizing such activity. We also come up with alternative lyrics if we can, like when in the “Wild Rover”, the narrator sings that he spent all his money on whiskey and beer, we made it a ‘wild baby’ (what with having a relative newborn) who spent all his money on wipes for his rear (it will help to understand this reference if you know the tune

Rascal: I saw KISS in Allentown back in, oh, 1989? Not fond of them now, from a content standpoint, but that’s true of most of what I listened to back then.
