The continued assault and battery on radio with progressive house music has been relentless over the last year. I think the sound is so new to the mainstream listeners they still have grown tired of it yet. Many EDM fans already know there are tons of great artists out there who have never been heard on the radio and they are ok with that, it adds a sense of exclusivity that you have to retain when something goes mainstream to avoid the overall prostitution of the sound. Usher along with a handful of R & B artists have welcomed the blending of progressive house and soul music and its worked extremely well for them. Usher has worked with David Guetta and is now offering up his efforts with Swedish House Mafia & Alesso. The tracks that have leaked are "Numb" & "Euphoria", "Euphoria" was produced by SHM while "Numb" has SHM sharing credit with Alesso. Take a listen and tell me what you think, I think it sounds brilliant and I could listen to Usher sing over stuff like this all night long.
