According to Mitsuda, the music of Xenogears belongs to the traditional music genre. Though he first described it as stemming from "a world of [his] own imagining" rather than any specific country, he has also claimed a strong Irish or Celtic music influence. His musical approach for the original soundtrack was to insert Celtic influences into "easy-to-listen-to" pop tracks rather than making either "dense" Celtic music or simple background music.
The album contains a mixture of vocal and instrumental tracks, and combines Japanese and Celtic music together in its pieces. The album's title refers to two ideas, with one being "a message to those who feel they have lost sight of their ambitions for the flood of information this era surrounds us with" and the other an affirmation to himself that Mitsuda had "rediscovered [his] own path". Mitsuda felt that with this album, he had "discovered the precise mode of musical expression [he] was seeking within" himself and "given form to the belief within [his] heart".
