Yeh thats what im trying to say, I don't see it as a new track. I reckon it would be a song like "From little things big things grow" (you might not know it but its an aussie song) which contains numerous artists doing a verse. Or even like the song Evie 1,2 and 3 by the wrights which contains numerous artists from different bands
But then again there could always be One artists makes a song for an album and they all combine and sell or something.
Who knows
