Jellysickle was pegged along time ago to the the first "single" for Everready, was before B2B dropped. Time has passed on that, track is too old. same for The Beast...would make for a great video and even a club track (hot ass beat!), but ultimately, song's been around for too long.
Caribou Lou...that would be a good choice because it has a hot beat, a rememorable hook, and overall it's an anthem. good for the club, and pop and some urban radio might bang it. i don't want to see another "club" clip from tech, but if 'Lou' is a single, you know he'll be in the club.
The rain would also make for a good single, a 3rd one anyway. you know the whole formula: 1st single is big enough, 2nd single is way bigger, and 3rd single will either be just as, or almost as big. at times, first 2 singles are big, and 3rd one is eh, especially if the 2nd is So big, the shit sticks around for months on end. B2b got aright reception i guess, but the key is to make the 2nd and 3rd ones stick.
worst comes to it: 2nd) 'Midwest' w/ Twista 3rd) 'Lou' and 4) (optional) The Rain
