@larsman - its absolutely possible. Even though I mentioned jazz as my primary pleasure, this adventure has led me to appreciate rock music that I otherwise would have not enjoyed without the exposure. That's why I referenced the largeness of the universe of music that what may be old for some can be new for others.
I don't question the worth of genres of music. but there is good and bad quality within all genres.
I grew up on 70s/80s R&B. No matter how I try, what passes for new R&B is just lacking. IMO the level of real musicianship - from vocals to instruments - is just absent from new R&B, thus my preference. It's not the old music that is preventing me from enjoying new music ... it's new music.
