Second the new trend for which I m really against is - songs sung by kids. By that thing a company can earn a good amount of money. But there is nothing for music in principle.
For example, a kid sings a love song, which he can not sing in that way as the persons who already felt that love feelings. Regarding sad, kids do not know the feeling of sadness because they have not gone through such situations.
U might have understood what I want to say.
