Interesting, and if true, something to fight within yourself (according to moi), because there is so much out there. I don't suffer from it, although see all the time people who apparently do.
On the other hand, it just occurred to me, perhaps by "tastes" these experts don't mean particular artists or genres, but something more general in music, that by which Pandora "scientifically" selects music for you based on an analysis of your taste AND an analysis of their experts, musicians and musicologists of their, Pandora's offerings.
I can't believe I'm about to link to The New York Times for this piece (and I hope I'm spared a zot for doing so) but here goes: Is 14 a ‘Magic Age’ for Forming Cultural Tastes?. Actually, long before that article was published, I've heard from other sources that for most people preferences in music and food become hardened between the ages of 13-16. Using a universe of one (me) as a metric, it's true. If I hadn't already become accustomed to something by then, my "taste habits" just stubbornly remain in place. That's probably why the 1960's music revolution just passed me by and why I still prefer smoother sounds to this day.
I also place a high value (maybe even too high) on the politics of the artist. I'll shun music produced by known leftists even if their artistic skills are otherwise without fault. And likewise, I'll give a break to those to those whose talents may be a tad subpar if they're Christian and Conservatives. That's why my favorite genre of music is Southern Gospel which even some of my colleagues at church find not to their liking.
