That may be the only song you like, but he has 3 albums that are considered definitive hip hop classics and has more or less singlehandedly changed the course of the genre multiple times. One of the most - if not the most - influential hip hop artist of the century so far.
I thought Yeezus was crap (I enjoy abrasive music and other more harsh hiphop acts like dÃ¤lek, Yeezus was a very halfassed patchwork of an album tho) and The Life of Pablo was only marginally better in terms of personal enjoyability. The sound lacks the cohesion that was present on his better efforts like My Beautiful Dark Twisted Fantasy, Late Graduation and 808's & Heartbreak, the good songs are few and far between, and while lyricism was never his strong suit, there are some moments there that are straight up embarassing. Unless he returns with something of the same quality as My Beautiful Dark Twisted Fantasy, I'm inclined to think he's a spent force.
Hence why i said my opinion. Maybe why i prefer old school artists.
