Need help to find music :)

Does anyone know the name of that one song mumbo uses in his videos? I know thats like the most unhelpful, unspecific thing ever, but its most used I think when he's doing redstone. The best way I can describe it is 'thinking music'. I just want to find the song, listen to it, and go: 'huh, that's neat' and move on, happy that I know what it is.
