Through the years I’ve often ‘tried out’ forms of music which are new to me, but I still come back to my rock/pop base. I like some classical music and listened to a fair bit as a kid, but I’m happy just listening to Bach if I fancy some CM (although I do like Copeland a fair bit too). I was very into jazz once upon a time, but even then a lot of it left me totally cold and now Robben Ford’s, blues tinged stylings are mainly what please me. I did try opera and I just don’t like it, with the exception of Carmen (but then I also find musicals trying). As Coilte said, it either appeals to your ear, or it doesn’t and I’m not sure you can train yourself to like something that doesn’t float your boat in any way originally.
BTW, I love your avatar, Barking Spiders; I have 4 chums called Alan, 3 of which we’re all in the same band
