It gets played a lot in documentaries, the NSPCC also used to use it in their ads. I reckon its one of the most licensed tunes, its definitely the Eno track thats been most licensed.
Aphex Twin did various ripoffs of this track a long time ago, with varying degrees of success.
Also Deepinder Arvo would never be quite that cheesy with minor chords. ;) What bugs me about this track is I swear Bach wrote it first. I'm not saying Eno ripped it from a Bach piece, anyone who writes music ends up writing something Bach already did eventually as he wrote so bloody much. I wish I could find/remember the Bach piece though.
