The lowdown on Bust A Move:
In Japan, the creators of what we know as Bust A Move named the game according to its characters taken from Bubble Bobble and put them into a puzzle game; thus in Japan, the game is known as Puzzle Bobble. When domesticated for American sales, Taito changed the name to Bust A Move to Make it more marketable to the American audiance.
Now, for the dancing game we know as Bust A Groove, the game was created in Japan and released under the name Bust A Move. When the game was ported over to the U.S., the name had to be changed because, of course, there was already a game titled Bust A Move, so the name was changed to Bust A Groove.
Usually people who have been playing these games since they were released, like me, refer to the games as Puzzle Bobble and Bust A Move (sometimes refered to as BAM) respectively. When you go to buy Bust A Groove soundtracks, they are still entitled by the Japanese name Bust A Move.
There's the backstory as to why Bust a Groove is refered to as Bust A Move. If it's confusing people I can change it ^_^
