Dope beat with a lot of energy I can't really hear 21 on this since the beat has a lot of energy a lot of 21 beats a slower and more dark but this is still very dope I can hear someone like Logic freestyling on this or ASAP Rocky.
i like it, pretty standard dark trap stuff, i do think 21 could find a pocket on here but it would sound better overall with a more aggressive rapper. great beat, keep it up!
