well hello ppl this song is very nice hiphop music type with a nice touch of boy band type music. though i am not much into indian music an'all but this one is definitely one of those which can be played on stage. i have not completed the chords involved ((which i will soon)) but these are the ones extracted by my chord recog. software F# Bb C#, 4 trained musicians it's enough i think, 4 untrained ones i will post the full song with chords soon && yes use the "cyclic strumming with reverb & delay setting" this definitely creates a nice ambience for this kind of song. if any additional chord is involved please mention.
