Yaschas Massif was bossa nova. One of the things I love about XIII and XIII-2's soundtrack are how many new genres have been injected into what felt to me a rather unchanging musical horizon for the series. Jazz, pop, rap, metal, techno, blues, downtempo, lounge, trance, classical, rock, ambience. I love it. The eclectic nature of these soundtracks, especially XIII-2's, is laudable.
