I found that my interests expanded with exposure… but some stuff just does not appeal to me. I started with rock in the 60’s and 70’s… then jazz, classical, blues, electronic, world…
There is usually a gateway album… one that bridges the stuff I like with a new type. Then when “I get it”… and slowly a whole new genera opens up.
The biggest gateway for me was Michael Franks. I was mid twenties staying in a cabin on Lake Tahoe doing research (I was a geologist). I went to this tucked away high end cool restaurants hidden in an old growth forest. One of his albums was playing… it completely changed my world… opened it up.
I have run at opera many times… I am just not going to like it. Mozart… not happening… Shostakovich just sends me into a dream. Coltrane… not happening.
There is so much music… some you will just not like… it’s OK. Worth giving a try every once in a while, but life is too short to waste too much time on something that doesn’t appeal to you.
