Hi , i'm not a hindi speaker , but i know 2-3 things ,
So lets see : in this song you have “aa bhi jao” , which isn't equal to “abhi jao” . “Jao” is the movement verb , it can either be used as come or go , depending the other words that are accompanying this word “jao”; however , indeed , used alone it usually means “go” . “Aa bhi” and “abhi” are totally different and opposed words . “Aa bhi” is equal to “aao”(come) , but a different word form , with same value, formed by “aa” and “bhi” , and it means ” come” , (come right now , come nah) . On other hand you have “abhi” . This word is derivate from the word “abh”( now) by adding as a suffix “i” and it means now( this very moment).Therefore “aa bhi jao” means “come now” and “abhi jao” means “go now”. I hope i helped lil bit .
