What A Time To Be Alive is expected to challenge another Drake album for music's biggest opening week of 2015.

If You're Reading This It's Too Late did 541K sales plus streaming back in February, and now Drake's mixtape/album with Future is expected to do 500K, according to projections from Hits Daily Double.

The last time two artists of Drake and Future's stature got together on a collaborative project it was Kanye West and Jay Z's 2011 effort Watch The Throne.

That album did 436 K first week.

Drizzy and Mr. Hendrix are expected to beat that, even though it's much harder to sell anything in 2015, their figures are from a short five day week, and so far WATTBA is only available on iTunes.

Impressive, indeed.
