Soft/gentle versions of top 40 music?

I went to a yoga class and the teacher had this nice, soft music playing. But it was all like top 40 pop music. But like acoustic or something. I should’ve asked her what playlist or station she was using but I forgot.

Anyone have any ideas where I can find music like that?

**ETA: it still had the words. Not just instrumentals. And I’m not sure what to google or search for in you tube...
