Seniors, it’s almost time to graduate. The last four years brought with them some great songs, and some really bad ones. For every “Call Me Maybe” and “Drunk In Love,” there have been countless songs like the “Harlem Shake” and “Gangnam Style” over the past four years. This year was an improvement over the last, and a much better way to go out. So, this week’s Music Monday features the best songs over the past year.
