I don't want to make a big detailed review, so I'll try to be brief.
MC-OG's should've done a re-take on his first verse. It was hard to hear some of his lines halfway through because his enunciation wasn't as strong. His second one was real good though, so props for that. Star had a consistent flow and delivery, but I don't think his lyrics were better than MC-OG's (I would've preferred more lines like that Special Olympics flip and less lines like the 'I'm calling Nicole, getting some tonight" or whatever).
I've been meaning to sit down and really give an in-depth review, but I don't want to drag this out anymore. This was generally even, but I'll give it to OG for his lyrics.
