As expected, Kendrick Lamar‘s untitled unmastered debuted #1 on the charts with 143,804 copies sold (182,029 with streams). 2 Chainz semi-collaborative effort with Lil Wayne, Collegrove, debuted at #4 with 35,340 copies sold (50,735 with streams). Both albums were digital only releases and may get a boost from their respective physical releases, but don’t expect much back-end promotion for either album.
