To be honest I will believe SHM are on board when I actually see the receipts

The same with deadmau5
They are like the biggest names in EDM across Europe and have genuine underground street cred. It would be huge to have them on the album. It's not like Guetta who has always aspired to be in pop. Working with Rihanna is something deadmau5 fans especially would definitely be surprised about ( / not approve of).
