I am writing this in support with Hari who wrote "WHY CHOOSE SHANKAR-EHSAAN-LOY?" 
I too as a fan am hurt after reading the article by Mr.JK Arasan. 

I don’t think there is anything wrong with SEL taking their turns in Kollywood. They have provided some class music and are undoubtedly the best in Bollywood!!!

Their songs have been chart busters whether it is their Dil Chahta Hai, Kal Ho Naa Ho, Lakshya, Bunty Aur Babli, Kabhi Alvida......., Don or the recent hits Taare Zameen Par, My Name is Khan, Rock On, Zindagi Na Milegi Dobara.

And if they aren’t given a chance to prove themselves in regional cinema how come they will prove it. 
I think they are the best and we should give them a chance
