The appropriate playlist which spoils what they're singing if you don't recognize the notation.

So two of my favorite games of the past decade I both played this last year. Wandersong (which is currently half off) and Songbird Symphony (which is also on sale, but not as much since it's newer) both of which revolved around the main character being a talented singer and spreading happiness in their quest, and both with extremely emotional scenes using (arguably, since the Lyrebirds are usually referred to as Songbirds) the title track. Also they're both HECKING CUTE and are musical puzzle platformers, with Wandersong being a longer RPG and Songbird Symphony being much more of a rhythm game.

TL;DR, these games are great, I made a fan art combining them because I greatly enjoyed both them and watching Barry play through them, go buy Wandersong and at least watch the VOD for Songbird Symphony (because it's great and all but a little short so while I recommend it, only if you're okay with paying the 'support indie devs financially please' fee.)
