Probably because I don't understand a word of it and didn't grow up with it.
I don't understand a word of it either -- it's in Telugu, which I don't speak, and the first 17 minutes don't even have words (it's a purely melodic essay). And I didn't grow up around Western music either, but I still listen to and enjoy that. The difference being that in either case, I have a theoretical understanding.
Granted, listening to performance of Western music doesn't demand the theoretical understanding that it takes with other systems. It's designed to be approachable to everyone... people often forget that the music of Mozart or Bach was the pop music of its era. It's designed to play to a very generic crowd and has largely simplified and lost melodic complexity over the years in favor of harmonics and layering.
In a crowd of 200 listeners at a classical concert, very very very very few (often zero) people really understand something about music, the others will be pretentious yuppies who let it wash over them and quote whatever someone else says when pressed for an opinion. In a crowd of 200 listeners to an Indian classical music concert about 100 will have Bachelor's or Master's Degrees in Music, and 20 or so will have Ph.Ds, about 10 or so will be skilled performers themselves, maybe 20 more will be people with music minors in school, and the remaining few will be the children of various others among the group. People who can read within a single note that you've transitioned from 8:1 to 27:3 time (which he did a few times in that song, which I know you didn't pick up on). Which is why over the years Indian classical, Chinese classical, and other older Eastern musical systems have grown in complexity on all aspects over the years, particularly in the 20th century.
Compare that to an example of the same type of music from a school of rendering krithis that was
2 generations prior, and the difference is quite apparent (though that is from a performance in the UN, so it was sort of "Americanized" to make it easy on Western listeners, but the vocals at least are still relatively canonical for that era)... even
1 generation prior, you can see the difference both ways...
