Bonus Songs are extra songs unlocked by spending money earned in-game. They can be purchased by going to menus (they vary by game), or going to the Options menu from the main menu, and going to the Store option. They will then appear on all of the bands that are on that game disk. On Guitar Hero I, II, they appear under the main set list. On Guitar Hero III, they can be accessed by hitting the blue fret button. Guitar Hero Encore: Rocks the 80s does not have any Bonus songs. While some videos have the song Because It's Midnite listed as a bonus song, this was only a demo and did not appear in the final game.
