I love Mashups. I’ve heard some crazy out of sync mixes, with one song pretty much barking at the other. Every once in a while, you can come across a mix that gets everything right, from the tempo to the decision on which song sits in the background or foreground.
The following piece of magic (accredited to YouTuber BobMills) mixes Lorde’s “Royals” with Nine Inch Nails’ “Closer”. It’s a great fusion. Enjoy.
