"Popular" just means that a lot of people like it. That's a pretty run of the mill use of the term. It doesn't mean it's a major cultural trend in a country. I just said it's pretty popular worldwide.

No, you said it's the "most commercially successful music genre".

I'd love to see a citation for both the claim you wanted a citation for and for your claim.

I sat in a Pizza Hut in CP Delhi loudly playing country music.

American songs play on everybody’s instagram stories. Not super niche.

And I sat in a chain coffee shop in Hyderabad that played the Brandenburg Concertos in a loop. I still wouldn't claim there's a Bach Revival underway in India.

pop music in general is somewhat popular specially in the bigger cities in India. never heard country music playing anywhere though, dont think its that popular as you claim.

local music (bollywood number, south indian film industry etc) is expectedly far more widespread and american music pales in comparison in terms of popularity
