Subject: Basic Version Working
X-Git-Url: https://git.r.bdr.sh/rbdr/lyricli.rb/commitdiff_plain/d3e32008ba762c8c00bfd99453e794ba68f40464?hp=-c

Basic Version Working

Working properly enough to retrieve lyrics when used with the
arguments method. Still, there's no practical way to use it for
now, so it doesn't really matter.
