Revert the removal of the song/artist values from list items for now.
The current plan of removing extraneous values from songs and albums
only works if I add multi-select and a dedicated menu button, but that
is still in the air, and in general I want feedback before I go ahead.
Aside from reverting the previous changes, this actually standardizes
all item descriptions under a single bullet point formatting system,
instead of the mix of commas and bullet points that existed beforehand.
