Most of the time when someone creates a "remix" for an r&b song, its' usually just sped up with a faster beat. As far as I'm concerned, the best house music remix for an R&B song(I've heard) was Debbie Gibsons' One Step Ahead. It came out in 1990 and sounds amazing today. You can't even recognize where it came from, and I love it.
King Britt seeks to do the same with Solange. I already love her sound, and King Britt takes it farther.
