I guess it's not really an introduction because it's been up for a month, but I've created a new Youtube channel to house all the soundtracks of 9064 games. That includes those of unreleased games, as well as unreleased music tracks from existing games. For Logan Kart, that includes extended and beta versions of some of the music tracks, as well as some of the sound effects previously unavailable on the soundtrack.
