Need help with Greek Club Music!!!!

So the past summer I went to many of the clubs on the isles of Greece. The music was great, but i don't know who or the names of any of the songs. All i know is that the songs were by someone that spoke english. Pretty vague, i realize, but i'm looking for anything. Thanks!

Do your remember at least with kind of music it was? i mean, it was more like pop, rock, ...???
And secondly, was it a band or just a singer?
