While this isn't particularly exciting for those who already have these songs, the strong rumours of new Crush 40 remixes and a blurb from CD Japan offers a hint that we may get some extra Zebrahead tracks in some form.
"Look back on fifteen years of "Sonic the Hedgehog" with the best vocal songs from each of the previously released "Sonic" games. Includes unreleased tracks, CD debuts, the latest remixes, and even bonus tracks from some of today's hottest artists!"Whether or not a Zebrahead bonus track or new remix of "His World" will crop up is as of yet unknown. Expect more details on the tracklist as the release date gets closer! Here's hoping!
