Bride refuses to play MIL's AI-generated wedding song, leaving their relationship strained days before the ceremony: 'It's not appropriate'

Is it wrong to reject a sentimental gift if it doesn't fit your wedding?

Let me answer that for you: no, it's not! Absolutely not. Listen, I only hope that one day, I get to have a wonderful mother-in-law because some of the stories about them are just pure nonsense. If I were the OP, and it was my wedding, I'd not feel bad at all for refusing to play an AI-generated song that's only going to embarrass me, my fiancé, and his entire family in front of almost 200 people.

I'll say, though, is it a wedding without some family drama? And I don't know why, but mothers-in-law are the ones who become the stars in every single conflict that emerges from a wedding. It's just they are so entitled all the time, thinking the event is more about them than the couple that's getting married. I understand they might feel emotional seeing their babies get married, all grown up, but that doesn't justify an immature attitude towards the daughter-in-law, in this case. 

And, something that I also noticed, is that the partner (the son of the MIL) never has a comment to say about it, or decides to put his own mother in place. Quite the opposite, actually. They tend to avoid those kinds of problems, as if they weren't their own, and continue with their lives. No matter the position he's in, or how entitled the mother is, I believe he's the one who needs to reject the song, and not his partner, who earned the anger and the silence from his own mom.

Weddings are supposed to be fun, and a moment for the whole family to get together and celebrate the couple. It's not worth it to be arguing about something so childish, like a 5-minute song that's not going to be played. I think maybe the nerves make everything more upsetting, and people tend to be more sensitive around these kinds of events… But, it's still a wonderful occasion to leave the egos aside, and to all contribute to make that night a one to remember forever.
