As for me I could do with some more pop-music from the 50 60 and 70ties,
hardly available on AM/FM.
The audience group of SW is 40+ and dominantly male, so some uptempo top
40 muzic from the past (not just the major hits as played by the Gold
stations) could be an alternative

not only that, but how about the top music from the 50's, 60's, and 70's of
each country broadcasting on shortwave? That should give some musical variety.

Being a shortwave listener, I have heard music from Africa that would never be
played in the U.S. at the time since it wasn't the kind of music that was
popular in the U.S. at that time.

And have heard other types of music from other countries. such as oriental
music.

I haven't really listened to shortwave much in years though, as my radio broke
and I didn't have one that worked for that band until recently. So I'm just
getting bacxk into the shortwave radio listening hobby.

So I'm not really sure what the shortwave bands are like today ) the types (or
formats) of the stations.

When I used to listen in the 70's and 80's, it was mostly news.
