The Song

Way back in the distant 2009, the video-game Dragon Age: Origins came out, featuring a vast and epic fantasy storyline. Now, here's the interesting part: at a key moment during the story (perhaps three-quarters in, right before the climax) the bard in the party, going by the name of Lelianna, sings a gorgeous Lament: https://www.youtube.com/watch?v=EAANKFPchtA
Now, this game's developer, Bioware, had often paid for the rights to use a song that someone on the team really liked to play during the credits, but this is the first time, as far as I know, that anyone commissioned a full scale song to appear as an in-world creation of some character within the narrative. It didn't stop there. Bioware kept featuring songs like that in every sequel they produced (such as the particularly catchy tavern ditty 'Enchanter come to me'; https://www.youtube.com/watch?v=_gtFtH3sW-M) and other companies started taking notes. Bethesda featured a couple of bard songs of their own in, their juggernaut of a fantasy game, Skyrim. Somewhat more recently, CD Projekt Red , when they were making, their Magnum Opus, Witcher 3, they featured this very clearly Lelianna-inspired ballad: https://www.youtube.com/watch?v=823yuWz0lto
Which, in turn (and in my humble opinion), must have inspired the Netflix adaptation to feature Dandelion's 'Toss a Coin to Your Witcher':

Pish posh, you say? Hogwash? Balderdash? Hah! Then how do you explain, that when I watched Amazon Prime's Wheel of Time last Friday I ran across THIS?

Now, the only thing remaining is for us to speculate what will the big Song be in the Lord of the Rings TV Series? What would you like it to be? What do you expect it to sound like?
