My music player automatically downloads lyrics for songs when I first listen to them, and one thing I've noticed is when there's a word the service they use can't make out it's notated with [?] so I listen to the songs and read the books from the albums and strive to finish the lyrics... it's like a secret hobby that I do only for myself, since my edits are only saved to my PC. I'm also really good at catching their misheard lyrics (because I check the books lol).
