7. "Cups" by Anna Kendrick
Despite the awful piano tune that’s playing in the background of this song, every time this comes on the radio it is literally impossible to not sing along to. Not to mention that you immediately start banging on the nearest surface (whether it’s a bar, table or your steering wheel) in time to the cup beat. Also, what’s awesome about this song is that it comes from a movie-musical (for those of you living under a rock this past year, the movie is Pitch Perfect). Kendrick herself can’t even believe that her song, which she learned from watching a viral Youtube video, has hit the number one spot.
