Hey guys!!
I was just watching hum toh mohabbat karega and i noticed that a song from that sounded like a song from mission istanbul...i know its werid but it does sound exactly like it.......

i cudnt find the the HTMK song from youtube so i found it in this site:

Listen to the music at the startin and the line that says:
Tumhein Chaah Ke Mere Haseen Kuch Aur Phir Chaaha Nahi
Haal Ye Hua Jaane Kyon

And then go here the mission istanbul song:
http://www.youtube.com/watch?v=9bH65tnEp24

this line songs exactly like the line from HTMK:
Jo Gumshuda Aankhon Mein Hai
Jo An Kahin Saanson Mein Hai
Dastaan Wahin Labzo Mein Kaho..

What do you guys think?😊
