Florence and The Machine. I'm sure we can agree on the fact that these guys have had numerous solid productions. Spectrum is no exception. Yet, some may argue that their original version was a little slow, lacking life. Calvin Harris successfully fixed that 'issue' without changing the song to much. He kept in place the dreamy lyrics, the inspiring synths, and even one of the beats. It's unique for a remix to improve a song and yet maintain the essentials of the song. Good Job Calvin Harris!!!
