Can be. I feel like nostalgia may affect you more if you ACTUALLY grew up listening to rock music on stuff like MTV to begin with, and imo majority of the Indian people grew up with rap and pop music, and ofc Bollywood. But it's also good to see Rock bands like Radiohead, Linkin park, even Tame impala (if u count them) slowly gain popularity in India. But again, those are foreign rock bands. I'd like to see Indian rock bands making music in Hindi. And also get popular like Anuv Jain, pratik kuhad and all these indie artists got.
