It's another solid gold fact that putting crowd noise underneath a song makes it more exciting by a factor of a million (conservative estimate). The KLF never mentioned it in "The Manual (How To Have A Number One The Easy Way)" but they did it on every single one of their songs. Look at the liner notes to The White Room, and it's right there: They sampled crowd noise from live albums by U2, The Doors and - if you can believe it - Haircut 100. It works. Every time.
So imagine a Coldplay song that's been given an explosive rave enema AND had the sound of an enthusiastic audience slapped all over the top of it. Well, you don't have to imagine it, because someone has done it for you. Here's the Hardwell Remix of Sky Full of Stars:
Disappointingly, this turns out to be a live recording of a DJ playing the song to a crowd of tanked-up holiday revellers. The studio version of the remix is precisely 25% less brilliant, but an improvement on the original, nonetheless.
