Kanye West first linked with Daft Punk when he sampled their track "Harder, Better, Faster, Stronger", for his Graduation single, "Stronger". He then fashioned his "Glow In The Dark" tour after their "Alive 2007" set-up (aka the one with the giant glowing pyramid), and most recently worked with them on multiple tracks from Yeezus.
Somewhere along the way, Jay Z linked up with the robotic duo for this track, "Computerized". While we're not sure when this unreleased track dates from, it is rumored to feature production from 'Ye.
Judging by Jay's flow and excessive Blackberry references, we're assuming this one is from the Blueprint 3 era. We all know Hov uses a Samsung these days.
Daft Punk have had their share of fake tracks passed around, and it's still possible that this also falls into that category, but one thing that speaks to the song's authenticity is that we've never heard these Jay verses before.
Start mackin' on my Blackberry
She got jealous
I was tappin' on my Blackberry
So she didn't keep in touch
And I can't tell the difference
We didn't see each other much
