I have a mustache.

I'd argue that the best type of remix/mashup is one that basically incorporates rap with any good song...very broad, I know. So here's a random assortment of mashups that do just that:

Mojo ft. DJ Clutch - Dangerous ('Hey Oh' Mix)

Matt & Kim - Daylight (Troublemaker Remix feat. De La Soul)

The Hood Internet - Soulja Boy vs Digitalism - Crank Dat Pogo

DJ E - Intro Like This (The XX vs. Mims)

DJ Bless - Transformin’ Fireflies (Owl City vs Lil Wayne)

Dirty Disco Kidz - Pretty Lights vs Westside Connection (Mr Physix Mashup)

PANTyRAID - Beba (Cool Catz & Shotgun Radio Remix) 

And this last PANTyRAID remix I've been meaning to post for a while now, but I couldn't figure out which post to include it in. I guess this is the one.

Freeland - Do You (PANTyRAiD Remix)
