Actually talking about RedOne as an individual is pretty confusing because it seems like in fact they are a team
http://www.redoneprod.com/team-red/ with a looooot of different people who worked on differents songs, if you take Gaga's example, it says that Bad Romance and Alejandro were made by some guy whereas Judas was made by another guy. But yeah RedOne is supposed to be a moroccan composer so i'm reallllllly confused about that, i mean who actually makes the songs?
Here's what i read in the booklet :
XOXO :
music & melody by Ameerah A Roelants, Yohanne Simon, John Mamann, Rush Aziz, AJ Junior
produced by De Paris and Rush for RedOne productions, LLC
Mixed by Trevor Muzzy for RedOne productions, LLC
That's why i'm not so confident when talking about "his" works because actually there are a lot of people involved and they did some songs that i know that you would never guess it's RedOne's sound
But since i liked XOXO and MOWY i'm sure i'll like the next one
