Pop singer Selena Gomez (USA) usually gets top billing on the songs she releases but such is not the case on her current hit "I Want You To Know". Why, it's because she's teamed-up with boyfriend DJ/Producer Zedd (D), providing the vocals on his song. So like most songs since EDM has exploded, the DJ gets top billing and the vocalist gets mentioned as "featured". The song has made it to #1 on Billboard's Hot Dance/Electronic chart. Enjoy!
