Probably not much for me. I still listen to people like Springsteen, Van Morrison, Electronica, 80s bands etc. People I tend to have "found along the way" aren't really that different. I've always liked anything with a Latin rhythm, whatever the genre, so no change there. Likewise "late night jazz". It's been a constant.

On the dislike side, I still can't get away with Classical, especially Opera.

Not really *changed*

Expanded a great deal and that continues

I still listen to some old favourites

Some change has come about listening to music "I don't like" because it has been made so well

I'd like to think my musical taste (and I use the word "taste" lightly) has grown over the years. For instance, it took me a long time before I could appreciate "classical" music, rather like acquiring the taste for red wine rather than just having the Liebfraumilch with everything. 

I've always loved blues, due mainly to a cousin who played in a blues band...which I eventually joined.  That and stuff like Free, Purple, Zeppelin, Hendrix et al was the score to my formative years.  Since then my tastes have encompassed reggae (a definite no no to the crowd I hung with at the time) and I was "into" punk from pretty much the start but I was just as likely to buy a Warren Zevon album as something by Wayne County, The Clash, or Elvis Costello.  Oddly, I also started my sonic love affair with Emmylou Harris and Eagles at around the same time.  I think my next great "leap" was due to Uncut magazine, which debuted in 1997, and I've continued to buy to this day (just taken out a new 2 year sub in fact) and has introducved me to artists I would never have come into contact with otherwise.  Extra big thanks should also go to John Peel (right back to the Perfumed Garden shows) and Bob Harris.

I could write a lot more about the various forms I've come to love (and hate) over the years, but with age comes experience, and in my experience I can quite easily bore the arse off folk once I get started on my favourite subject, music.

Been into prog since i was 14 years of age. ive Not changed that but in the early 90's i contracted an additional disease while spending a full night in a music tent at a music festival, out of it in the form of the all new European  trance music {Not the utter tripe you get in night clubs} but the underground variety not really heard of in the UK at the time. However early prog is still my love.

My tastes have. Started out with listening to Duke Ellington,Count Basie and Louie Armstrong with my Dad then "progressed" to the chart stuff(we all did!!) then moved on to listening to a lot of dance music as that was the culture of the time. Working in different clubs kept me pretty open eared though(that remains the same) and now it's very little dance music and a huge mix of anything that appeals. I like a wee trawl through the what are you listening to now thread and a browse on Spotify/Deezer is good. The constant is that I enjoy quality music.

What he said, for both !

As with most others, not really changed but developed and expanded. I still love the music of my youth and play it often. My main interest has been music of the past though and the strange thing is that most of it is from someone else's past, not mine! I was around in 1967, for example, but I wasn't listening to semi-obscure west coast bands or japanese rock music, or even The Doors or Janis. I liked heavy rock as a teenager but I was also exploring things like CSNY, Neil Young, Love and Zappa -things that my demin jacketed cohorts frowned very deeply at!
Getting interested in hifi widened my taste significantly and that was the time that I discovered Miles Davis, Dexter Gordon and others.
Next up, I suppose would be my rediscovery of classical music. I had grown up with it around the house as a child, loved much of it (probably through familiarity) and then rejected it in the way that is only right and proper for any self respecting teenager. I started going to a few concerts which I greatly enjoyed and, if I am honest, thst is the way I prefer my orchestral music to be presented. I rarely play it at home, but love the performance.
Early blues has been a major part of my diet since becoming interested in the social history of the south of the USA. I loved blues since my teens, but my passion for it became heightened once I learnt a little about its origins.
That's part of the story, I don't want to bore you any more.

Keep on seeking out new stuff, dismiss nothing until you've heard it (but still respect it even if you hate it) and look back as well as forwards.
