No clue what the name could be
 

So I have this song stuck in my head FOR AGES and I really need help cause it's gonna kill me otherwise, it's a kind of chill-housey vibe with mainly marimba used, I heard it on some obscure CD mix one of the gym trainers uses for stretching, which is called something like Stretching The Wild but of course she has a copy of it so no songs list. I tried using Shazam to no avail. It has no lyrics to help either
It has a couple varied parts to it but the most prominent one is a marimba bit that goes something like:
du dududu du du dudu du dudu

Please help me, if you have any clue what it may be
