A$AP Rocky’s debut album Long.Live.A$AP leaked a full month before its scheduled release date in January. Whether the premature leak of his album will hurt his career or not, it has only increased more interest in the buzzing rapper. One of the most anticipated songs was “1 Train,” which boast appearances by Kendrick Lamar, Joey Bada$$, Danny Brown, Action Bronson, Yelawolf and Big K.R.I.T.

During an interview with VIBE, Pretty Flacko discussed how the posse cut came together. He names K.R.I.T.’s concluding verse as the most impressive one.

"I said all of the young cats of my era, not none of the old hot niggas,” he said. "The young cats who I respect eclectically. I just look at it like, all of them had something different to offer and bring to the table as far as delivery and style wise. Everybody sounds like an original, nobody is rapping like modern-day rapping."

The full version of A$AP’s other posse cut “Pretty Flacko (Remix)” is also another track to look out for. While he hasn’t spoken on his album leak yet, you can still pre-order it on iTunes. Long.Live.A$AP hits stores on January 15.—Eric Diep
