I'm imagining toddlers growing up to hate their parents' music taste, because they already fucking hated it when they played it to them when they were a fetus in utero.
The dad hyped up "fuck yeah I'm gonna teach this kid to love Slayer because I'm playing it to him now when they're in there!". And then they hate it like "THIS IS WHAT THAT SHIT WAS, I HATED IT ALL THE FUCKING TIME, FUCK YOU!"
Like there was for a while the whole "Play Mozart/Beethoven to your kid in the womb and they'll be smarter" and shit - there's no way everyone universally likes classical music. I know several older people who don't enjoy music at all, which just seems bizarre.
It's not like every kids gonna pop out and be like "That Mozart's Requiem was some shit, man! Play it again!".
Young kids do not have the mental capacity to differentiate between "I learned something new" and "I always had this opinion". They are simply incapable of the former position.
There are psychology experiments with children that show this effect, it's pretty wild.
I would sing my daughter Johnny Cash in NICU. She loves it now. Best part is the chords tend to be easy if she wants to learn to play, or if I ever want to learn LOL
The original You Are My Sunshine had something ridiculous like 48 verses many of which have been lost and it went on for twelve minutes. Though I forget where I read that, and I can't find it again, so it may have been some kind of weird fever dream.
People should sing whatever songs they want to their kids. Kids understand that the lyrics aren't necessarily supposed to be taken literally or even applied to them; kids just like the attention and how relaxing it is to listen to the most comforting voices they know sing songs that they love.
My wife sang our kids "You Are My Sunshine" and "Puff the Magic Dragon." I sang them love songs, break-up songs, songs about death, and everything in between. The only difference in our day-to-day life and personalities is that they are developing great taste in music and that I spent much more time singing to them than I would have had I been bored to tears singing "appropriate" songs.
At 3, I already had a kid I hated. I know this because apparently I saw him one day, made sure to point him out to my parents and blatantly told them I hate him. At least that's how my mom tells it.
3 yo me was right to hate that kid. From age 3 to senior year, that kid was a Grade A douchebag.
