Magnolia is posted constantly and Jason Molina still gets threads made about him even years after his death. It deserves the promotion. The fact that people aren’t immediately calling OP a pleb speaks volumes.
Also, consider that the mucore chart is pretty diverse and generally includes records that are very specifically the linchpin of their respective genre. Among the Americana, folk, and alt-country fans on this board, Magnolia is universally and uniquely beloved.
