I'm going crazy trying to find out what this song is... I think it might be quite famous because I recognised it immediately when I heard it today but I was in a restaurant and it wasn't that loud so couldn't Shazam it or anything...

anyway, I don't think it has many words except for a part where it sounds like african voices or something chanting "oh ah-ah ah!" (with each ah slightly stepping up in pitch)... I don't really know how else to describe it so I realise it's not much to go on, but it is kind of chilled and echoey, almost ethereal sounding - kind of reminds me of africa by toto but in a slower more chilled way (and with less words)

PLEASE help me its driving me mad...thanks!
