"SHAMROCK" is the fourth album released by Hayashibara Megumi. Much like Hayashibara's second album, all of the songs found on "SHAMROCK" had tie-ins with different anime series. The first press edition of the album came with a 40 page, hardcover, photo booklet. This is Hayashibara's first album to include contributions from some of her longtime collaborators such as composer Okazaki Ritsuko and lyricist Arimori Satomi.
The majority of the songs were used in the All Cutural Purpose Cat Girl Nuku Nuku OAV (Ganbatte!, COMET rendez-vous, ROCK de Ikou, and Only One) and Mahou no Princcess Micky Momo (4 Gatsu no Yuki, Yume wo Dakishimete, and Suki Yori Daisuki Minky Smile). The song "In The Fluffy MOON Nite" is an English language version of Hayashibara's "Haruneko Fushigi Tsukiyo -Oshiete Happiness-" single.
On 2005.03.16, a limited edition re-release was issued along with all of Hayashibara's other albums up through the VINTAGE albums. This version of the album featured all the tracks remastered and a 24 page album booklet, and a 16 page photo booklet, all of which located inside a special box.
