With so many songs now have one main singer and a second featured singer. Can we add in a secondary artist to help with separation. Like the new Justin Bieber song, which features Ariana Grande. If we can add the second singer, it would hopefully prevent an Ariana Grande song to appear back to back with her song with Justin Bieber. This is done in commercial radio stations for artists like Sting, who is also listed as a member of the Police.
