Yeah, learning curve is steep at the beginning..

Something on these lines should do:
def update_metadata(m) =
[("artist", "quartz presents")]
end
quartz = map_metadata(update_metadata, quartz)
By default, map_metadata only updates metadata. Thus, in the above, we
only have to return the field we want to change.
Also, had you wanted to append some string to the artist, you would
have done for instance:
def update_metadata(m) =
artist = m["artist"]
[("artist", "quartz presents: #{artist}")]
end
Good luck with your scripts!
