Hindi song in "Inside man" !!

We were in the movie theatre to watch the new Denzel Washington movie "Inside man". As the main titles came up on the screen there was an all familiar audio in the back ground -" Jinke sar ho ishq ki.." from Dil Se !! It was totally unexpected. We never heard anyone mention it before and at first we thought it was playing by mistake. But then as the titles rolled on the whole "Chaiya Chaiya" was playing in the background.
I will be interested in finding out how Spike Lee ( movie director) ended up with the Sukhwindhar's number from Dil Se.
