Now it can be seen that Himesh is actually smiling whilst singing this song, and this feeling was also felt while listening to its OST version (whereby one can imagine such visuals).
For example, hear out the starting vocal alaap OOOOO in O JAANA LUVE U MISS U from ROCKY - THE REBEL and one can imagine his visual expressions whilst crooning it (whereby he literally pours his heart out). Hope that one day he would sing this part live too to depict what I mean. Hence, Himesh - the singer is a true professional who does justice to da song's requirements rather than just crooning its lyric lines just for da sake of it.

It can be seen from his facial expressions as to how much effort in terms of input is required for this particular line, outstanding commitment and dedication to his craft in order to extract da right mix of emotions.

Bottomline
In this Damadamm unplugged performance, Himesh has sung these unplugged songs in 2 - 3 scales lower than their respective OST counterparts, with his 'middle octave impact' vocals due to which the songs sound damn catchy
This does not take anything away from the OST that was already good, but this unplugged song versions just strike a chord, win over da listeners and bowl / woo them over.
As the original title of da film Ishq Unplugged suggested so, yeh toh kamaal ka Damadamm unplugged ho gaya boss.
