Burn, Can't Control The Kids, Hello Heartache, Supernatural, BBD and Bring The Noize. 
Crazy Kids did deserve more success, but at least it was a Top 40 smash. 

I kind of had a feeling that they'd remix it with will.i.am a while before it was released as a single because he produced it, and I was sad to see when I was right. The only positive is that it helped the song more in the UK since they use will.i.am there. The Juicy J remix was nice, but the original still should have been released initially all along.
Overdose is fantastic and it shouldn't be underperforming but because of Epic... well you summed it up. Made In The USA is an average song and I like Heart Attack better, and I knew that they'd pick it as the second single because they're so predictable but there were like 3 other more obvious smashes on DEMI.
American Girl. I was so pressed when this flopped. I honestly thought that it'd be 2013's answer to Call Me Maybe. But there was too much 2011 and not enough 2013 with this track, which is basically the only reason why it flopped imo. Oh and Epic of course. Rock N Roll should have gone Top 10, it's such a great song, and I actually do love the music video - it's wrong in all of the right ways. Deserving winner.
Looking forward to the rest of your countdown.
