Himesh composes well structured vocal alaap theme pieces in his sufi rwak songs, which is one of his typical sufi rwak traits.
Out of these, his BEST EVER is:
> OOOOOOO (HISTORY KILLER MIDDLE OCTAVE ALAAP) from start to 0.20, 1.33 to 1.43, 3.20 to 3.30 & 4.37 to end in O JAANA LUV U MISS U from ROCKY - THE REBEL that simply bowls over da listener.
Reason:
Apart from being catchy in terms of composition notes, it has a strong EMOTIONAL CONNECT / KONNEKT simply for da way Himesh - the singer croons it by LITERALLY POURING HIS HEART OUT (dil-o-jaan daal dete hain), conveying the desperation feeling of a weeping lover who lost his beloved one due to separation, especially from 0.05 to 0.10, 0.16 to 0.21 & 1.39 to 1.43
This feeling can be best felt by CREATING A VISUAL PICTURE MAP IN YOUR MIND / IMAGINATION of Himesh crooning this alaap BEHIND DA MIKE i.e. how he would have exactly crooned it in his recording studio in terms of his facial expressions that would have resulted due to his overall effort in terms of giving it his everything if you would have witnessed it live in reality, and nothing else will be required to justify this fact.
Also hear out da power of da resonance in his vocals at 1.34 (play at full blast from 1.33 to 1.35 for da full magnitude of this goonj at 1.34).
Da overall combo of 'himesh literally pouring his heart out' with his 'middle octave croons' results in a unique overall alienish sound at this selected pitch range frequency.
