This songs from the voice commercial and soon show. In the song there are piano 
voicing which create a specific sound. So the intro sounds like D , Bm, A but its 
not a Bm its G with a B in the Bass get me.

Cause when its time ill
                D             D D G/B  A    D.....

So thats pretty correct i recomment the G/B over just a normal G chord and the A/
C# because you get the right harmonic movement and it feels and sounds better. 
Though if you left them out it wouldnt sound wrong but not as good from my 
perspective.
