As the title says, do it. I'll start things off with something that'll be hard to top.

* it's a beautiful duwang outside.
* birds are CHEWing.
* it feels like a picnic.
* on days like these, highschoolers like you... SHOULD BITE ZA DUSTO.

This speaks for itself.

Someone did a beautiful compilation of Laika's movies, from Coraline to Kubo. Spoilers, of course but another warning: You might cry. I know I did.

Meanwhile, pretty much as a response to the upcoming release of Logan, another bloke did a rather heart wrenching tribute video of High Jackman's Wolverine over the years. And of course, it's set to the very music used in the trailer for Logan.

This is probably the most perfect mashup i've heard imo. The 2 songs just mesh so well and I love it.

I dunno.

On the one hand, that is a really damn good mash-up, and they do mesh well, as you stated.

On the other hand, Blumenkrantz is such a good song by itself that I'm conflicted on marring it with a mash-up.

And on the other hand, I view Kanye as cancer.

So I'm really conflicted on this vid. >.o

I love that one, though I feel the same about Kanye. He's garbage and his music sucks, but mixed with Blumenkrantz it's actually pretty enjoyable.

kanye is a good boy & did nothing wrong

I enjoy <<www.youtube.com/watch?v=kLddzj5-pPU|this one>>. Funny, yet strangely soothing.

This one's so good, the original creator thanked the remixer,

You're not kidding. That's a solid remix. I love it. :D
