Ok, after digesting these some more, here are my predictions on the next two singles. I based this on how much the songs have hook-wise for the respective formats. They definitely are trying for a pop hit here on this CD, given some of their material, so it almost seems obvious that Cinnamon is going to get rolled out. And they'll need to offset that mushy single with something a lot harder to reinforce their rock fanbase (which will probably be pissed about Cinnamon if it's all over their girlfriends' radio stations). Thus, Fast As I Can seems like the easiest rock song here to promote.
CHR & HOT AC: Cinnamon (First Kiss On Mars second choice)
ROCK: Fast As I Can (Peacoat second choice; Take A Load Off would be a perfect single except for the too-long repetition of the title in the song)
