I used to feel the same way. Got started with light classical but over the years got to appreciate deeper forms.

@JackPedigo Yes, well my eldest brother, once top scholar of Eton, never strayed into pop music and was doing stuff at a music retreat manor I think at Hitchin when I was rocking to Cliff Richard. The gap remains as he takes in the Ring every year at Glyndebourne whilst Ifootle around on my guitar in the back of beyond.

@rogerbenham I liked some pop and even rock bands. I try to be open. My late partner was from Iran and her middle Eastern music was played often. I was stationed in Turkey and once showed her my ignorance by comparing Iranian music to Turkish. Was not a high point in our relationship but I did get to listen and even enjoy Iranian music. Now, I tear up when I hear it.

@JackPedigo: Yes, I bet you do. Although I had contact with Sufis and even once played along with a band of them, I really can't say I like their music. I'd not know Turkish from it either. Same with Indian. I loved chanting Hare Krsna and after doing that for a couple of hours one gets high as a kite, but I only can take Indian music in small doses. My wife had been to Pune a few times and she had some good quality stuff but a little Deva Pramel went a long way. I can listen to vast amounts of cathedral singing especially a capella16th and 17th century stuff. I never tire of Palestrina but hardly post it here because it does not seem appreciated. Maybe you have to have been a cathedral singer to know what it is like when that is being sung all around you.
For a time I just burst into tears when I sang the songs that I sang with my wife.

@Ray13 No, not academic educated but musically educated. But of course some (maybe you) just appreciate it naturally. I was educated in music at schools and mostly taught myself. I went to many concerts in my London days 69-74 which lead me into loving Baroque and generally not any longer so keen on Classical.
Definition: Baroque starts around1550 and ends with J S Bach. Classical starts with C.P.E. Bach.
I rather think we entered a new form maybe with Delius. Certainly I love Preisner and Gorecki but that is far removed from Beethoven.
