I read about 432 frequency in music and started wondering about this myself. I personally stopped listening to most music except for some classical for a few months now and have discovered my taste and tolerance changing as a result. I can not stand country anymore when before I enjoyed it socially. I no longer want to listen to metal, which has always been my music of choice. I now lean more toward acoustic stuff like Jack Johnson. Maybe I'm not angry or depressed enough to relate to metal and country or maybe they were making me angry and depressed. I have reached the conclusion that music should enrich your life and make you feel good and if it doesn't, I don't bother with it. I would enjoy reading any long term studies done about the effects of music on long term behavior. All I can find is stuff about 432 and it is full of conspiracy mumbo jumbo.
