Jazz listening has dulled my taste for Rock...you?

Funny, when I was in my 20's I listened to a lot of jazz, now I am in my 50's and find it boring and only listen to it as background music.
I would much rather listen to rock, blues, folk, or classic.

Most pop music, including rock, is very repetitive. Yeah, there might be a guitar solo in there somewhere, but unless the lyrics are really deep or really clever, there's not much else going on.

Good jazz, by contrast, is endlessly inventive, so it can hold your interest longer.

That said, I probably own roughly similar quantities of jazz and rock CDs (and a lot more rock LPs, because they partially predate my own shifting musical taste), and listen to both about equally. It depends on the mood.

The bulk of my collection is rock-always has been & always will be. One of my very good friends is a jazz aficionado & has turned me on to a lot of different jazz over the years & although I enjoy it, I listen to & enjoy rock as much as I did in the 60's.

So the answer to your question is no, jazz has not dulled anything.

Poor digital transfering, and the voicing priorities of many high end components can really hurt some pretty good (especially rock) recordings. Apart from that, the last few decades have produced thousands of releases that help to blur or reconfigure the descriptive verbage and alot of the arbitrary boundries that we try to impose on music. Miles Davis, Zappa, McLaughlin, Holdsworth, Torn, Fiuczynski, (and many others) have delivered the kind of visceral whomp that most would describe as rock without confining themselves to established rock idioms. Some stuff that might be thought of as rock is often way more challenging and sonically complex than most of what is in the BMG or Columbia House jazz catalogs. The old Duke Ellington truism about there only being two kinds of music seems to hold. Well informed or not, the listener will decide if the music is good or bad/(boring or interesting).

Yep, I'm a jazz mostly, new age and world music guy. Once in a while I "toss on a little rock action" but go right back to the "other stuff" in less than 5 minutes !!
HAPPY NEW YEAR !!
