If you're a music fan, one of the rules is that there must be one song each year that becomes your Song of Summer.
Criteria for a successful Song of Summer include originality, catchiness and general sense of fun. Ability to play the song about eight zillion times in a row, preferably in a car without a roof or at least with the windows all down is a must.
I think I've got my pick for this year…
