Add a subreddit flair for songs with human-written lyrics.

Tangentially related to u/Bea-Billionaire's post about no one giving "a sh*t about anyone else's music." I stopped listening to anyone's songs here because lyrically, I'd heard too much AI-generated garbage. If I knew some actual thought and even 'craft' had gone into writing the lyrics (and the song didn't have the 'meme' flair) I'd be more inclined to listen and provide feedback. So please, admins, hear my plea.
