watch the video I posted above. Garcia and Teenwolf talk about how Diplo asked them if they had any new music they could use. They sent over what they had, and Diplo sent them back the track but with M's vocals on top.
like I said previously, I know a lot of songs have multiple producers involved. But I tried to limit the options to one person, and seeing that Garcia and Teenwolf had a larger part in the production, I decided to list them for just UB
