CD
A CD is a special item in the Wii game, Super Smash Bros. Brawl. It appears randomly througout all parts of the game. Thus, it may appear in the Subspace Emissary, VS Mode, or any other game mode in the game. When collected, it will allow players to add more music to their selection of My Music tracks. Other than this, the item has no other amount of significant value. The item can be comparable to the Trophy or the Stickers, as it is a collectible that is found randomly across the game.
Trophy Information from Super Smash Bros. Brawl
Each stage in Super Smash Bros. Brawl has several songs prepared for it. You can set the percentage chances for which songs appear in My Music. It's fun to choose songs according to your tastes. Each CD contains one song to increase your music library. Be sure to grab them when you see them. Once you've got all the music that's in the game, CDs will stop appearing.
