All 2015 chart toppers in two reduced mashups …

There's still more than a month and a half left of 2015 and we're already starting to be inundated with year-end recaps? Blerp, wake us up when it's Spring 2016 please …

This one is solid, however. Each year Daniel Kim of Pop Danthology creates a massive mashup of the year's hottest tracks (read: nothing obscure, sorry hip kids), blending each of them semi-seamlessly through a block of memory's worth of chart toppers. But this year's is a bit different than submissions past:

“I found myself cutting down so much of the original musical pieces just to ‘jam’ in as many songs as I could,” Kim says in a statement released by CollabCreators.com — a viral content creating site. So he chose to cut the lengthy track into two parts, even making shorter versions of the already trimmed tracks for YouTube viewers.

Listen to both the SoundCloud versions and YouTube versions below.
