I remembered a lot conversations about this topic so i'll share some others opinions here and my opinion about it.
So, i've talked about this topic with my parents and some friends. And my parents and school "friends" say that classical music (all the baroque, classicism, romanticism and more) are great to your brain. My friends say all the music help people, no matter what genre it is. Some people find help from pop music, some from metal and so on. So, i'll tell my story about music and what i personally think about it.
I got through all music genres in my life. So I'm friendly with all of them. But one genre, which had helped and saved me a lot is electronic music. More precisely, these artists: Avicii, Otto Knows, Martin Garrix, Alesso, Axwell /\ Ingrosso, Swedish House Mafia and multiple genre artist- violinist David Garret. They helped me to achieve a lot of goals, they had inspired me a lot and they helped from severe downs. I don't know what I've done without them. I'm really happy that this had helped me a lot.
I'll say that all genre music helps people. It can motivate you, help you or increase your IQ. No matter what genre, it can help you one or all genres.
