Cutting to the quick, the producers she worked with include RedOne (on first single "Bad Romance"), Rodney Jerkins (!!), Teddy Riley (!!!), Ron Fair and Fernando Garibay.
It makes more sense after reading this bit from her statement about the upcoming not-so-rehash:
“I spent a lot of nights in Eastern Europe, and this album is a pop experimentation with industrial/Goth beats, ’90s dance melodies, an obsession with the lyrical genius of ’80s melancholic pop, and the runway."
Well, I for one hope the Teddy Riley song(s) sound just like Hi-Five's "I Like The Way (The Kissing Game)." That would be new jack swingin'!
But let's just hope the Rodney Jerkins stuff doesn't resemble anything like Janet Jackson's last album. Becauser that would be...monstrous.
