Southside (808 Mafia) roasts beats from Discord

In celebration of the launch of his new King of Trap Vol. 1 sample pack, Southside joined us at Sound Factory for a unique challenge.

In the video above, Southside sat down with us to rate and react to beats submitted by producers via Discord—and he’s not holding back. From hard-hitting trap tracks to unexpected surprises, see which beats make the cut and which get roasted.

Watch Southside cook up a beat of his own in our previous video with him below, and to be a part of future producer reactions, beat battles, contests, and more, be sure to join the Splice Discord.

And there you have it! Whose beat was your favorite? Who else would you like to see react to your beats next? Let us know in the comments section of the video, and subscribe to the Splice YouTube channel for more producer-led tips, tutorials, and challenges.
