Seems like Dil Lagaane Ki Saza from Ek Rishta is inspired by, of course a pakistani song, Deewana Deewana from Deewana Tera Pyar Ka. however it not a blatant copy, or even a full lift... but the inspiration is fully there.

and relevent portion of Ek Rishta song is main tera ho chooka hoon/deewana main deewana parts starts from 0:50
