Not here for remixes, tbh.

Touch the Sky//Soul Meets Body and The New Workout Plan//Title and Registration

These are amazingly well done.

Will these be uploaded on Spotify?

I hope so , but I don't think they will because there will be some legal matters to be sorted out first .
They are not making money out of soundcloud uploads so they wont be sued by kanye.

If this gets enough media attention and love from fans then they might consider

Is it official or just some mashups?
