2013's "1Train" was a Royal Rumble of the hottest rappers at that time: A$AP Rocky, Kendrick Lamar, Joey Bada$$, Yelawolf. Danny Brown, Action Bronson, and Big KRIT. The production by Hit-Boy explodes and never lets go. It was my favorite rap track of the year (looking back at my Top 100 Songs of 2013, I listed Kayne's "On Sight" higher as a rap song which I still stand by because it's one of those Kanye as Radiohead comparisons I tend to make - no one could make that song but Kanye, no one could envision something like that):

So now it's 2016 and we need another 1Train! This beat is filthy, first off. In comes Danny Brown, the shrill rapper, with a track off his new album, Atrocity Exhibition, with a who's who of the hottest rappers: Kendrick Lamar, TDE label-mate Ab-Soul, and the reclusive Earl Sweatshirt.

No surprise that the best rapper alive, Kendrick Lamar, KILLS the hook and then kicks his verse down the stairwell. Ab-Soul's verse is a bit too Watch the Throne-ish with his Balmain and BAPE talk, but I find it hard to hate on the man, I love his flows. Danny Brown is an acquired taste.

Then there's Earl Sweatshirt, who finishes in a tie with Kendrick, mainly with the closing line, "Well it's the left-handed shooter / Kyle Lowry the pump / I'm at your house like / "Why you got your couch on my Chucks?"
