Another year, another load of pop music releases, many of which you probably didn't get to listen to. But, since 2009 that hasn't mattered because ever since then DJ Earworm has been making his yearly mashup of the biggest pop hits.
Seamlessly weaving them together he takes listeners on a journey through fifty of 2015's most popular songs, according to Billboard's weekly Hot 100 charts, anyway.
They include songs you've probably heard like Adele's "Hello," Drake's "Hotline Bling," Mark Ronson ft. Bruno Mars' "Uptown Funk" and plenty of stuff you probably haven't.
It's a great way of getting the flavor of the year in pop without having to, you know, listen to each track from beginning to end. Plus, it's an annual end-of-year tradition as much as complaining about Christmas coming earlier every year.
If you missed it, you can listen to 2014's United State of Pop here.
