hey i recognise it, but i dont know what it is, sorry :(
it's not just some backing music made specifically for documentaries and stuff no? :/
u should try Shazam, if u can get a recording, or use that recording without the voice, u can call 2580, i dunno if thats just a mobile phone u can call it from though? but basically u play the music down the phone and some computery thing might recognise it :) sadly, it doesnt always get it cause there is a song i want and it didnt get it :(
