Anyway, I ranted a couple minutes ago about how remixes have to be improvements or changes unique to the original song. I thought I'd give an example, so it looks less like I'm just pulling this junk out of thin air. so here's a remix by probably one of my favorite remixers, TheFatRat. He's pretty amazing, and his remixes are very well-tailored to the original song, while still being drastically different. A remix can really breathe new life into a song, and TheFatRat does a great job at it!
So here's a great remix he did of The Knocks' Brightside. Enjoy!
