Why does 'Repeats' Repeat themselves Repeatedly?

Why do I get to hear the same ragas and same songs in most of the concerts nowadays.

Kambodhi and Karaharapriya seems to be everyone's take this season.

If the artists themselves get bored of repeats, they seem to find happiness and content in Bairavi or Kalyani.

Despite great efforts taken by Legends like SKR and S Rajam and many others, why is that none wants to take up many rare and vivadhi ragas.

Even Reethigowlai and Varali seems to be the major 'Sub-main specialists'.

I hope these people must read "Sangeetha Vishayam" article written by Bharathiyar before their performance.

(TNS' tape singing in the next room -  "Ethanai Kettalum Podhum enbadhey illai" in Bairavi :'(  )

Why dont you take diversion buddy?
