This Most Popular Videos Of 2015 Mashup Is Great, But We Think They Forgot A Few Gems — VIDEO

Every year, YouTube creates and releases a tribute mashup of all the viral moments our video-friendly Internet culture consumed and created. This mashup of the most popular videos of 2015 does not disappoint. From highlighting the fun-loving Left Shark to the adorable, sassy, 6-year-old Johanna Colon, dancing to Aretha Franklin, the nearly 7-minute video is set to this year's most popular pop songs and hits on (almost) every memorable viral moment.

According to YouTube culture executive Kevin Alloca, the video took 21 days to shoot, enlisting the unlikely viral and YouTube stars alike. Alloca told Business Insider, "Some of these [YouTube Creators] are pretty huge stars who are busy with crazy schedules, so to have them in the same place is really fun."

The video is listed as highlighting over 90 videos or YouTube channels, so don't feel bad if some of the references go completely over your head (because they definitely did mine.)

And while the video is obviously awesome, the creative powers at YouTube did miss a few videos that rightfully deserve to have their place on the end-of-the-year list. Here are the videos YouTube missed that we definitely don't want to forget as we break ground on a new year.

Cop Singing "Shake It Off"

This is just the most adorable thing you've ever seen and, honestly, a little needed.

Miming Through Time

I'd imagine the Australian comedy sensations couldn't be part of the annual Rewind because, well, they're in Australia.

All The Lip Sync Battles

The Tonight Show With Jimmy Fallon has lit the Internet on fire in 2015 with their hilarious, dramatic and (arguably, at least in some cases) artistic lip-sync renditions of popular songs.

The "Clash of Clans" Superbowl Commercial

I'm going to go out on a limb and say that copyright issues kept this hilarious commercial out of the mashup, which is a shame because it was awesome (and viewed on YouTube over 83 million times).

This Amazing Moment On 'Britain's Got Talent'

Can you hit that high note, because I cannot hit that high note and apparently 39 million can't either, because they watched Calum Scott do it instead.
