The fact that the 1.2 update that includes Jukebox feature does not include the actual music files required to complete the feature should be considered a BUG. For users who only play locally and not on servers, the game should not require the creation of a Microsoft Account to download "free" game content. Any free game content should NOT require a login at all.

Recommend that all audio for future enhancements should be included as part of the actual game update files. Would Mojang not include the game play sound effects? Of course not! This is no different since it is tied to a released game feature. This is not optional content such as skins or custom resource packs. Please fix this during next scheduled patch release.
