It's time, in these last remaining hours of 2020, to take in DJ Earworm's "United States of Pop" mashup — a yearly tradition, and one more way to nail shut the coffin on this abominable year.

DJ Earworm, who used call San Francisco home and whose year-end mashups were a mainstay on SFist for many years, has just dropped a 50-year medley that melds a few bars from 50 different songs — one for each year, in order, from 1970 to 2020.
