Minecraft is still getting new songs, but lategameTips.4 is not updated along with them.
Open “Minecraft for Windows\Content\data\resource_packs\vanilla\texts\en_US.lang”
Search for “lategameTips.4“
It says “Our music is by C418, Lena Raine, Aaron Cherof, and Kumi Tanioka.“. Missing Amos Roddy (Chase the Skies), Hyper Potions (Lava Chicken CD, if it counts), and fingerspit (Chaos Cubed).
