Martin wishes he could sing as good as Mr. Ocean  the alarm clock is annoying but it's also part of what makes this song amazing, it's about waking up from the fantasy of an idealized life and getting back to reality.
Oh and it's funny how people who say they "hate" Coldplay, but loves this song saying Ocean made it good when at least half of the song is still Coldplay. No other band seems so grateful to hate on these days, it's like "Coldplay is gay" works as a mantra, such an immature stance.
Amazing cover. And to you saying it's just a simple cover, it's not. He makes his own verses/melodies, it's not even like a regular cover. Makes his own stories just like his there will be tears over Mr. Hudson's track. Only thing that's identical is the beat
