Already in the first few bars, most will think: I know that from somewhere. And yes, the song contains a piano sample of Roxette "Listen to your heart". The melody has thus nothing to do, it just serves as accompaniment of the song.
I find the arrangement and lyrics and melody of "Hurts" very nice, I liked the song right away. Incidentally, Per Gessle of Roxette gave the Danish duo "Electric Lady Lab" personally his blessing to the sample and like the song. So can not go wrong!
