I find it hard to vote on battles like these cuz I don't think either of you guys were trying to be serious. Sounds like you two were just having fun lol. And let me just say, I was entertained.
Regardless, it's a battle, so I gotta cast a vote. Here are my thoughts. Spawn is right about that reverb in FB's first verse; it would've been better for him to take it off. And then when he does drop it in the second verse, he gets sloppy, and it makes it harder to understand him (although, it sounds like this verse has a different EQ setting than the first; maybe that had something to do with it?). Byron, on the otherhand, sounded consistent.
Lyrically, it wasn't all that impressive (but again, I don't think you two were trying to be super serious). FB even throws away his last two bars to blow raspberries. Milkdud brought his A-game though.
I'd think give my vote to Byron. But again, this just seemed like a fun battle, nothing serious. So yeah, I liked it. Good job to both!
And I'll be the first to admit that after listening to this on repeat for awhile, I actually felt like rapping to the beat, too...
