You know, there have been many, many truly outstanding AR songs of late that I can name - Hosana, Dil Gira Dafatan, Rehnuma, Arziyan, Omanna Penne, Genda Phool, Sajna, Muskura, etc. etc.
But, very few songs reach the ultimate pinnacle of utmost perfection, an impact so grand that the song just sweeps you off the floor, knocks you out, makes you bow to it. Now, of course, this is subject to opinion and interpretation, but some robust consensus has emerged in the past for AR songs in this special category I mentioned, such as Dil Se Re, Bombay Theme, Vande Mataram, Pacchai Nirame....the cream de la creme, the iciing on the cake, the greatest of the great. Two recent songs of AR that have claimed privilege to enter into that special top of the top category are Rehna Tu from Delhi 6 and Aaromale from VTV in my opinion. I know some may not agree with this opinion and that's fine. These songs demand attention, demand respect, demand devotion. It's the attitude of the song, the depth, the spaces between the notes, the sound, the feel, the vibe, the epic quality. When D6 and VTV came out, respectively, these 2 songs were raved about most in this group and rightly so. Aaromale and Rehna Tu, like Vande Mataram, Pacchai Nirame, Dil Se Re, Yeh Jo Desh Hai Tera, Bombay Theme, Khwaja Mere Khwaja, Piya Ho, and others, define greatness.
