Also please note with these kind of shows we are only getting people with good voices. They just sing songs which are already composed by someone else. They are not able to create a song. If a person practises voice training for hours and hours his or her voice is bound to become good but he/she cannot be a song creator or composer. WE ARE NOT GETTING GOOD COMPOSERS OR CREATORS OF SONGS.
Bob Dylan of USA had a very bad singing voice but he has been one of the greatest composer and creator of songs.
There are many Rock bands in India for both English, Hindi or Bengali songs and they create wonderful tunes and new songs. They have originality. I would rate them much better than the winners of these type of shows.
