song title help...

hey guys,

so i need your help once again concerning the world of music. unfortunately i can not discribe thaaaat good what i am looking for but i'll give it a try.

i am searching for an male artist, i am not sure but i think he is from the UK. the song was pretty famous, at least here in germany, i think something like 2 years ago or so?

the song starts with a simple but cool drum (basedrum and snare), a few seconds later a nice piano becomes part of the rhytm and the guy is singing the word "na" in a nice way...something like "naa nanana na naaaaaa nanana".

i'm not sure but the first words of the first verse are "some people...".

well it's a bad description i know but i hope someone can help me out :)

thanks in advance!
