"Steal my girl" definitely sounds different from the previous songs of One Direction, but by no means bad. The song has a bit more r'n'b in itself, also sounds a bit older than he is, but that makes him really well! The unique voices of Zayn, Liam, Niall, Harry and Louis come to advantage and provide an absolute hit! The "Acoustic Version" is really great, even if it is not a real a cappella version. The single you should definitely buy!
