A few days back, we heard the original reference track for Rihanna's #1 hit, "Work," sung by one of its co-writers, PartyNextDoor, and while we were happy to sit with that for a while, it seems that the track was just a signal that the floodgates had opened, with a number of unreleased PND records making their way online today.

Among these records are two songs that appear to be reference tracks for the If You're Reading This It's Too Late sessions. "Legend," being a sketch of Drake's opening track from the mixtape, and "647," which resembles Drake's "Company" from the same project.

Some have pointed out that a line from PND's "Legend" ("she knew me when the kid had waves") actually made it onto Drake's verse on "U With Me" from VIEWS.

Listen to "Legend" below, and the rest of the tracks here (Via XXL).
