Detachment from most of this stuff is the one way that a lot of people haven't tried--It's just popular music. I'm like Ragamuffin up there, I find it deeply uncomfortable to listen to most popular music, just like Mark Twain described Wagner: pretty good music but he couldn't stand the noise it made.
I'm personally no fan of Styles, or of Schonberg either. Give me Schumann any day, or Fritz Kreisler.
"Wagner has lovely moments but awful quarters of an hour." ~ Gioachino Rossini.
I'd agree most popular music is dross - it would have to be at the rate they churn it out, but maybe that's the process required in order to get a handful of really good ones. As we've established, there are some ghastlies among the classical composers too, but again maybe that's the make the really good stuff stand out.
Music is apparently the one art form that has the most direct access to the heart and emotions. The other art forms require a little more processing or intellectualisation - and some of them like books require a lot of processing. Which is why poets are invariably booed off talent shows before they can open their mouths, while singers and dancers are hotly anticipated and embraced. People want that immediate emotional hit, they don't want to work for it. Like children wanting dessert, not the peas and beans that are actually better for us.
There's probably as much diversity of musical tastes as there are tastes in clothes, decors, colour palettes, hair styles, cars and food. Most people can give you a reason for why they like this piece of music and not that one, but psychology disputes the extent to which we can know our own reasons for liking or not liking something. Our reason can sound plausible and socially acceptable/reasonable, but it's more likely to be a rationalisation. The real reason is likely unconscious e.g., 'this piece of music reminds me of happy, secure, comforting times at my grandparents' house when I was little'; 'that piece reminds me of posh people who look down on me so no, I don't like Beethoven'. The reasons are often linked to familial attachments, socio-economic status or situations that welcomed vs excluded us. Would be good to see some studies on these themes.
