Here's how it works now when you request an artist by name:
it adds all songs by the specified artist to the now playing list.
It doesn't clear the list first, and it doesn't start playing automatically.
feedback is appreciated on how best to handle this. I realize that the ideal would be to allow macros so that you can do what you want... but for now lets settle for a default behaviour,
i.e. - clear now playing, queue the artist, start playing.
and while we're at it, I know how to do the first two, but to start the new playlist playing at the first song, without first going to the now playing screen? I don't know how.
