The Ace Combat 4 Shattered Skies Original Soundtrack is the most revolutionary of all Ace Combat soundtracks to date. The two composers who remained with the Ace Combat Namco Sound Team Music Staff after AC3, Tetsukazu Nakanishi and Hiroshi Okubo, completely re-invented their previous music styles (such as ambient and electronic used in the previous game), to a mainly orchestral one. All Ace Combat OSTs since AC4's are still composed with orchestral instruments at its core. A choir was used for the first time in an Ace Combat soundtrack. Guitar influences from Air Combat and AC2 were also revived, this time featuring both electric and acoustic guitars in a variety of tracks in the score. However, the most notable event in the soundtrack's production was the hiring of inexperienced composer Keiki Kobayashi to the Namco Sound Team. The AC4 OST was the first major musical production that Keiki Kobayashi participated in, and his work in the soundtrack ultimately assured his promotion as Music Director in the Ace Combat series for the next games to come.

　　I have what I need...

　　I have so far to go

　　And only heaven knows

　　The sun keeps shining *Everything is bound to change*

　　And the wind keeps blowing

　　But the wide blue sky *Wide blue sky always the same*

　　It forever stays the same

　　I've been finding

　　that the choice it will make....

　　That the wide blue sky

　　that its never gonna change

　　*But I have so far to go*

　　*And only heaven knows*

　　*Yes I have so far to go*

　　*Heaven knows*

　　Not-ah one day goes by

　　Bring back my blue sky

　　On which I rely

　　Theres hope in the wide blue sky

　　*Wide blue sky*

　　*Blue skys given me so much hope*- Repeat 8x

　　*is the chorus/background voice"
