I refer to my latest playlist. In order for me to add a song to this playlist, the artist must been born in a country that will appear once in the playlist eg. England = 1 song, Welsh = 1 song, Thailand = 1 song, etc. The artist must be born from the country in question, but does not matter where they perform or live so in other words, the playlist has an artist from every country in the world. It must not contain any more than 1 song per country.
Where do I find assistence to help with the above?
