Add songs from "folklore" 🌲

Pretty self-explanatory. Google / Metrolyrics has good reliable lyrics. We just need to copy lines from there and trim out lines like Ah-ah-ah and oh— and stuff, and add it to data under the right titles as file names.

Oh--we also need to update the copy on the landing page with the new total number of songs in the system from "over 120" to something like "over 140".
