Seems like Ruling Me, Smart Girls and Uspoken are the most popular choices.... Oh and Run Away, less Trainwrecks/Time Flies love then I unexpected! I personally can't wait for a live version of Time Flies!
I can't pick a single favorite. But I can pick three.
Brave New World (Yeah, really)... lol
That's not to say the other songs are not great. I actually like them all, but I have already listened to Hang On like a billion times now and Unspoken a billion and one. So, you know, this is my current faves. It's always changing. However, Ruling Me is just plain awesome and should be a single.
