The Gloomy Galleon level music in Donkey Kong 64 originates from Dream: Land of Giants, the game that eventually became Banjo-Kazooie. Fittingly enough, it was originally intended to be the theme for Captain Blackeye, Dream's villainous pirate antagonist, who would later go on to cameo as a non-playable character in Banjo-Tooie's Jolly Roger's Lagoon world.

As a bonus feature for Rare Replay, Rare included a set of music tracks dubbed "Top-Secret Tunes", which primarily features previously unreleased music from Rare games in development, including many hailing from Dream. One of these is a rendition of Blackeye's theme, called "High Tides, Swift Sails". While Rare had made efforts to avoid any legal issues with Nintendo as they were putting together Rare Replay (such as removing the remix of the Donkey Kong Land boss battle from its version of Blast Corps), this song's appearance may be an exception as the original version comes from a game owned by Rare that was never completed, while the game the song was repurposed for was never planned to be included in Rare Replay to begin with.
