I like a combination of the three. I get tired of the 3:16+4:8 verse/hook combo. I like tracks where they just rip a sixteen, or a 32, but I also like song where they go for 100+ bars, just not all the time. But if someone's gonna do a 100+ bar song, they really oughta flip into different beats, ie Royce's Who Got Bodied. Doing songs the normal way is always dope too.
