Sonic Heroes had some of vocal tracks as well, so it warranted a vocals-only CD. However, not content with only 6 songs on a CD, they threw in some nice bonus tracks from Sonic Adventure DX. They're the standard character themes, but this gives you another chance to collect them if you didn't already have it.
