All those vids you've posted, never heard never seen. I am not sure if I liked them over Karma's vocalist's vocals, most of these singers sing the high scale on falsetto and I think that's more easy to do than not resorting to falsetto.

But I will have to agree with you because you clearly seem to know more about Nepali pop than myself (again, I am just a novice). There were two names you listed that I have heard and I think are better than Karma Band's vocalist: Anil Singh and Sabin Rai but they both are solo at this time and thus I stated vocalist of any band member.

Anyway, thanks for sharing.
