I don't like the way music is treated today. I do not want to associate myself to any kind of music tampering. People don't know what music means these days. Singers only shout and then they become famous and their songs become hits.I, for one, don't miss his voice and his arguments are easy to refute with Sturgeon's Law. But it underline how difficult the playback singing industry must be. Singers are at the mercy of music directors and usually, only one person is needed for a song. A significant Long Tail must exist, with "winners" i.e. popular singers or singers associated with current stars, taking the bulk of assignments. The 70s-80s were a prime example.
However, things seem to be different now. Many new singers (some from the endless carousel of TV 'talent hunts') have received prominence in the last few years, especially thanks to music directors like A.R.Rahman, S-E-L, and recently Amit Trivedi. The stranglehold of one-man-one-voice has dimmed with current singers unable to command the heights of the Kishore-Lata-Asha-Rafi era.
Not such a bad thing.
