Music is not language and it is not "a language". It is something that _seems_ like language. This is because music has evolved as a mutated copy of part of the human language acquisition instinct. The mood change caused by music is a mutated copy of the mood change that accompanies initial language acquisition, and it serves a different purpose. The mood change that accompanies initial language acquisition helps to focus the infant's mind on language as a separate important thing that has its own (somewhat arbitrary) rules that need to be understood separately from everything else. The mood change that accompanies music serves to intensify emotions that accompany daydreaming - this helps us to "better" daydream, in a manner that does not cause us to confuse daydreamed emotions with real emotions (because we are always consciously aware that the mood change is directly caused by listening to music).
