For me this is nonsense, there were always people who had broad interest in all music and I think the identity with a particular style of music is partly marketing and partly inhibition. Many people I know have all styles of music, especially since the arrival of MP3.
It seems to me anyone who feels that a genre of music defines them needs to be in a band, or to relax.
I like some of most types of music, pop ballads, punk, metal, classical, ska, reggae, RnB, soul, some jazz but don't actually listen to much music as I can't afford to buy it. I was wondering which category I fit in. I don't like all music, nor do I know enough of the technical details to recognise high technique. Friends who are in to music think I have no taste - if it sounds good I'll listen to it.
I do have absolutely no sense of rhythm and as a general theme complex rhythms, like experimental jazz, don't sit well with me.
No offends, but nothing to be proud of. Have you thought of taking some basic musical training and learning to play an instrument? I think it really helps to develop the musical taste and helps to understand and enjoy music deeper, which improves your life in many ways.
