Mine has to be Lakeerien song, then ye ishq nahi aasan.. and Tum ho..I think it's the same for everyone.😃
Lakeerein song just took off.... It's one of the reasons what made me love AkshAn! It's iconic. It took them to another height. Same with ye ishq nahi aasan..
I believe they're so underrated! Bet if these songs were used on other popular couples, there would be mad rage for them. Not fair. I remember Bepannah shows songs were hugely popular due to the couple.
Edit* - How could I forget Tum ho!
