In my opinion
HR's popularity may be making it difficult for other singers who are not in his gharana.His type of music has the support of most of the younger generation in India and that is why they may be voting for his students more than for others.
I feel that both Ujjani and Paresh may not have survived so long if they had been in JL or ID Gharana. Vineet is a good singer but he may have not got the percentage of votes that he has been getting, had not HR been asking the public to vote for him all the time.
Please comment.
