Pokémon Christmas Bash
This is a list of Pokémon theme songs that includes the media and release information, which is mainly about the American and Japanese opening and ending themes of the Pokémon animated series. They are as follows.
Note: Several episodes from the original series were not aired dubbed. See Pokémon episodes removed from rotation for more details.
Note: Shortened instrumentals of the theme songs were used as the end credit theme songs in the dub, starting from the "Diamond & Pearl" series.
There are many soundtracks from the anime. The following is just to list a few.
Pocket Monsters Sound Anime Collection: Music Collection/Famous Scene Collection (ポケットモンスター サウンドアニメコレクション ― 音楽集・名場面集, Poketto Monsutā Saundo Anime Korekushion Ongaku Shū Meibamen Shū?) is the licensed soundtrack from the anime. It was released by Pikachu Records on June 10, 1998, in Japan only. This collection consists of composer Shinji Miyazaki's orchestrated arrangements of musical compositions from the first four Pokémon games by composer Junichi Masuda and exclusive musical cues heard throughout the first series. These instrumental tracks are categorized as sixteen chapters included with the show's first opening theme song "Mezase Pokemon Master" and second closing theme "Pocket ni Fantasy" (both are the TV-size edits). Each of the instrumental tracks are followed by a brief commentary featuring Satoshi's Pokémon Zukan voiced by its voice actor Shinichiro Miki explaining each composition's association with the story and at what point it plays. Included with the album is a hard bound picture book (the Meibamen Shū (名場面集, famous (impressive) scene collection?)), stickers, and a merchandise catalogue.
