Ok so Dance Dance is probably a very obvious choice, I mean c'mon just read the title. A fun song accompanied with an equally just as fun video to go with it. This is Fall Out Boy at their peak and it is a song that I can always listen to.
~Honorable Mentions~
Good Time by Owl City & Carly Rae Jepsen:Some may say this is what I should've picked when given both songs but I think it is better as an honorable mention. It is a very fun song but it's kinda forgettable to me and I kinda forgot this song even existed until about a week ago when I heard it on the radio again, so it deserves an Honorable Mention.
(Sorry there's only 1 Honorable Mention, couldn't think of many songs)
