Everyone has a song that no matter what makes you break out and sing! That song for me it has to be "Sublime Santarea" but my daughters is "All About That Bass".

This man secretly recorded his wife singing Salt N’ Pepa’s “None of Your Business” and it’s adorable – especially her surprised reaction at the end when she realizes he’s filming. If my wife caught me doing this I would be dead.
What song always makes you bust out singing?
