Did I do something wrong or is my neighbor overreacting?

Ok so first off I am sorry I am only 20 and not Jewish and don’t know much about it. I just want to be respectful. Also if this isn’t allowed I am sorry.

A lot of folks in my new neighborhood are Jewish and my next door neighbor yanky is. I think his family is very devout because like once they asked me to turn on their stove because it was Saturday and they do all of the holidays and dress really conservatively.

Yesterday my sister in law and I were playing in our backyard with my son and listening to music. It was during the day, and weren’t super loud or anything, but they live next door so they could have heard us. But today Yanky came over and was telling my husband that it was disrespectful and that he doesn’t listen to female singers. It wasn’t anything raunchy I don’t think, just normal pop music.

I asked my uncle (this is his house but he’s retired and moved long story) and he said he’s never heard of that and there’s no HOA or anything like that so it’s not a rule.

I tried googling but got really confused. Can I just ignore this? I won’t be obnoxious or anything but it would be annoying to have to constantly be checking the music everytime we’re outside. But I don’t want to be offensive.

Thank you in advance!!
