This is not an actual song from the games! This IS, however, an original song based on the new Pokemon games: Pokemon Scarlet and Violet. It is a route theme, and the reason its "Route 340" is that the D-340 highway in Spain is the longest highway in Spain, so I named it after that. I am also streaming all my songs, including this one, on Spotify!
