My husband is jealous of old men?

Context! Me and my husband get along pretty well for the most part, but sometimes he has very black and white thinking which I just can't stand. He's a classical musician and insists on pretty much only playing classical music around the house especially around our toddler. I grew up listening to anything really, but especially rock, 80s jams and City Pop, my dad had a progressive rock band in the 90's and I am somewhat of a musician too and I play guitar and base. He doesn't oppose me playing on my own, but today he told me to stop playing Tatsuro Yamashita. I questioned why on earth he was nagging about that, and his reason was "first, its going to influence our son, second, i am the only Japanese man in your life" which made me burst out laughing (that's my stress response) which made him angrier. I told him that's the stupidest thing ever. How can he be jealous of musician, especially a senior citizen? (Tatsuro is 72!) His issues seems to be that this specific musician is Japanese, and my husband is jealous of that. He knows his jealous, but I dont intent to stop listening to my favourite music because of him. Ive also noticed him dismissing me playing musical instruments, especially when I play piano (his instrument) and I am afraid he feels insecure about me being a musician too? I have a deep connection to music, and it depresses me to not be able to enjoy it because the thought of his disapproval worries me. We resumed our activities, but the time will come when he will see me listening to my music and I want to avoid a fight!!
