can anyone explain this?

i've never heard of this song

That's 'cause it's not Coldplay ;)

who is it then?

is it a cover?

I read the lyrics and it sounds like a coldplay song. maybe it's new and this sinny guy somehow heard it and mis-read the title? Maybe it was played on a radio somewhere and he recorded it? a b-side? Who knows...

Play out the chords and see what it sounds like, I'm too lazy to do it :p
