A$AP Rocky's new album Long.Live.A$AP leaked earlier this week, and one of the most talked about songs on it has been his posse cut "1 Train" featuring Kendrick Lamar, Action Bronson, Joey Bada$$, Yelawolf, and Big K.R.I.T. Recently, Rocky sat down with Vibe to discuss the '90s feel of the song, and why he chose an "eclectic" lineup of new artists to be on it with him. He also says, "By the way, Big K.R.I.T. murdered that, FYI. Heads up."
