Some reflections having listened to this mix a few times:
1. They are both talking about love in the most part. Lovers not fighters. They're also telling stories, proper artists not novelty acts.
2. Thug is a little faster than Dean, I wouldn't be able to articulate the technicals, and it's not much, probably 10-20 bpms. If I had some cdjs I would consider pitching the one up and the other down and see what happens
3. You could swap the beats for each and each would still work. Makes sense to me that Dean has made beats for rocky.
