Jay Z & Daft Punk “Computerized”

Unfinished? Demo? Leak? Fake? It’s a Jay Z & Daft Punk collab though that supposedly didn’t make either Random Access Memories or Magna Carta Holy Grail. I think I may know why though: the melody sounds like a leftover from the Tron: Legacy sessions and Jay Z admits he has a blackberry instead of a Samsung in verse 2. I’m skeptical of this track’s legitimacy and at the very most, this leak has got to be from an old session between the two. What are your thoughts?

UPDATE: The song is also said to be co-produced by Kanye West.
