Remixes of the classics "Type A" and "Type B" musics from Tetris are featured in Super Smash Bros. Brawl as music tracks for the Luigi's Mansion stage, titled Tetris: Type A and Tetris: Type B.
This is considered a type 3 link because music is not supposed to be heard by the game characters, but only by the player, so only the players are able to see the connection between the two series.
In Super Smash Bros. Melee, they where able to freely reference Tetris Attack, being an original Nintendo game.
About Super Smash Bros. Brawl, while the classic Tetris music (an arrangement of Korobeiniki) was used in many Tetris games, it was actually an original creation from Nintendo, being featured for the first time in the Game Boy game, so they could use it in their original game.
