Quiet noise

So I’m making up a playlist of tracks that I class as “Background”. The type of thing that doesn’t vary too suddenly, isn’t too sad, and can be left to play for hours. The kind of stuff you hear in a million and one coffee shops across the world.

It’s for evening listening whilst the in-laws are here, stuff to fill the void instead of having the goggle-box blaring.

I’m stuck and need some suggestions. What do YOU put on for background music?
