I decided to dive into the many samples and loops I have found and gathered over the last many years. I never used them much before, but this song is completely made from samples. I have cut, pasted, reversed, shortened and chopped the samples, but for once I did not sing or play anything myself.
"Oh yeah" backwards sounds like "ha-a-ee-yoh". That sounded a bit tribal to me :0)
Lots of "ooh-ooh", "Aaah", "Yeah" and the likes of that :0)
Various Spanish and Italian phrases (I think)
