So, Mimi Smartypants posted a link to a site of Self-Referential Songs, which is in a WIKI format. I’d known of WIKIs, of course, and see them and whatnot, but I’d never tried to actually add anything to one.
I plunged on anyway, and edited the page by copying and pasting and making changes to the pasted stuff. And it worked! Yah me! Yes, there was a tutorial, and yes, perhaps I should’ve started there, but I’m pleased I figured it out myself. (And yes, I’m aware this is not rocket science).
BTW, I added “Lonely People” by America. :-)
