Please give more mounts a different piece of music past Borderless.

[Andevom]

This makes very little sense considering every expansion they add in 3 Savage mounts and 7 primal mounts with unique themes. And the final primal mount (e.g., Kirin, Firebird, Kamuy of the Nine Tails) also has a unique song. Clearly, they’re coming up with the space somewhere.

It's what Soken claimed. It's possible specific mounts (primals, savage, etc.) are always planned out space-wise to have a particular theme, but they don't have much wiggle room when it comes to changing it for existing mounts. That's purely speculation, since the question he answered was about changing an *existing* mount's music.
