Here we go, let’s see how ‘down with the kids’ you really are. San Francisco’s DJ Earworm has delivered his annual mashup video of the year’s biggest songs.

The four-minute video, called Do What You Wanna Do, is a compilation of the catchiest tunes of 2014. It has already been viewed more than 4 million times on YouTube.

It features megahits from Pharrell Williams, Iggy Azalea, One Direction and Pitbull, as well as Irish star Hozier.

Already feeling out of your depth? Don’t worry, you’re sure to recognise at least some of the tracks.

Anyway, the mashup is entertaining enough in itself. You might even find that like Meghan Trainor you too are ‘All About That Bass’. The kids will be well impressed. If not then just do as Taylor Swift would do and ‘Shake It Off’.

Enjoy the video.
