This is the best time of year. For his seventh year in a row, Jordan Roseman—better known as DJ Earworm—has released his epic mashup of the top 25 singles in pop music. 2013’s is called “Living The Fantasy.” Ever since 2009’s “Blame It On The Pop,” which still holds up as a masterpiece, his mashups have been a milestone for each year in music, giving us an idea of what we’ve been listening to and what each song has in common.
