A.R.Rahman has always said that he wants to break all barriers like religion, language, nationality etc., with his music. And, here is an instance - people in Uzbekistan may be dancing to "Kaadhal Sadugudu/Aye Udi Udi (Alaipayuthey/Saathiya). yes...Iroda Dilroz, a famous pop-singer from Uzbekistan has used this tune for her song, Sevgi Sedosi. Of course, with due credits to A.R.Rahman!

PS: Does anyone know what language is it? Found the lyrics here
