The Golden Era of Dr.IR and Dr.SPB

Also, one would see KJY / KSC / LM pics typically on music shops in KL (even in 80's / 90's the recording center culture wasn't there), who were primarily counted responsible for sale at those counters and not the composers...contrast that with TN of 80's

You have brought a very important point here... we all want to identify or highlight just "our" people. In youtube many Malayalam songs are simply highlighting KJY, Telugu songs highlighting SPB, Kannada songs highlighting Rajkumar and Tamil songs highlighting IR or ARR. If you read the comments for those songs.. you can see more than 70% folks are again talking about the greatness of KJY in Malayalam, SPB in Telugu, etc. etc.,

I think it is just human nature.
