Plot all songs from album / top songs from artist / all albums from artist

[fsktom]

Adjacent to #32

Add command to plot all songs from a specific album (either absolute or relative to the album)
in a similar vein: all albums from artist (absolute or relative to artist)

similar but more restricted: top n (max 20?) songs from artist (not all bc too many) (absolute or relative to artist or relative to album though I don't know if that makes a lot of sense)

Added way to plot all albums from an artist in c002ec7 plot artist albums

Used this to only show the top 3 albums by default. The other traces you have to manually enable. This is to reduce clutter. I'm gonna use this is in plots for top aspects I think #69
