"Ideally there should be fair mix of singing and marketing. But it is the latter that gets more importance and the participants get such huge exposure that they become celebrities overnight. But real good singing is all about everyday riyaaz and not hype," says the well-known singer who came on Indian Idol as celebrity judge on Friday. Sonu says he could not do the third season of the popular talent hunt show because of his commitment to concert tours in America and Europe. "But I had heard a lot about the show and the contestants and also watched a few episodes in bits and pieces. That is why I decided to come as a celebrity judge and was pretty impressed with the talent," says Sonu who was highly impressed with Emon Chatterjee's singing.
