The Sims 4 moving away from its kid friendly themes?

Not a fan of this song. I don't think it fits the spa theme at all. I think of spas as relaxing. This song is not relaxing. The first couple of times I watched the trailer, I had to mute it. I have watched it since, with the music. I still don't think it is a good match.

I don't think that this signals a more adult turn for the sims. I think it just signals that Luumia made the trailer.
