Post Twilight trailer music missing from in-game speakers?

[Birb（｡･ө･｡）]

A bit of a minor thing, and forgive me if someone else has pointed this out already. The trailer music found on the in-game speakers doesn't seem to have been updated since it was added in 1.11.2, meaning every piece of trailer music from after the Twilight pack is missing (Grasslands, Tropical, Arid, and Oceania). Its just a little thing that I'd love to see updated at some point, both for the sake of consistency and just because those lil' soundtracks are always so wonderful - I'd love to be able to listen to them without the background audio from the trailers. <3
