Disco is revived in this pop and R&B single by Justin Timberlake, who is very well-known to most of us.
As a music reviewer noted, this another "moving" song has some similarity with a Michael Jackson record. "Take Back...", then, is another piece of deriving formerly-used elements and stringing them together with modern ones into good music.
Here I remember dancing, since it's disco—revived/modern disco. And so I remember gatherings like a turn-over ceremony, a.k.a. prom, where I dream of mixing the songs throughout the night.
This just tells me there is still a very very wide room for retro music in me. Good thing "retro" is revived in music like this.
