For my own part, I've found that as I have grown older my musical tastes have broadened considerably (although I can never see it encompassing Rap, Country or Opera). I first really got interested in music in my mid teens (heavily influenced by my cousin) and for several years, I would only listen to heavy Rock. I used to wonder at that age if I would still like the same music as I got older. Now 58, I appreciate the skill and superb musicianship more than ever.
My Dad loved traditional Jazz, but I hated hearing it over the radio or his records. Then, in my 30's, me and my then girlfriend visited Ronnie Scotts Jazz club in Birmingham (sadly no longer there) and I was transfixed. Jazz like Rock, is a music best heard live. The ability to improvise (or 'Jam') gives it 'Soul', which I find missing in some other genres.
So, now whilst I still listen mostly to Rock, I'll also listen to some Pop, Jazz and Classical. For example, Adele's 'Set Fire To The Rain' is a song that I can listen to over and over again. The power and control of her voice is incredible along with the beautiful melody. Another is Bette Midler singing 'The Rose'. Again, a wonderful melody accompanied by the most beautiful and moving lyrics I've ever heard.
I'm glad that I have broadened my musical taste. There is so much great music out there, that I doubt one lifetime will be enough.
I forgot the Blues! How can I forget the Blues? I love the Blues!, Whether it's Blues Rock such as Led Zeppelin , early Whitesnake or AC/DC, or the likes of B.B. King and Buddy Guy (both of whom I've seen live).
