Ketsumeishi (ケツメイシ ?) is a popular four-member Japanese pop and hip hop group that incorporates singing and rapping into their music. They have had several major hits in Japan, including "Sakura", which reached number two on the Oricon yearly chart for 2005 and was featured in the Japanese game Taiko no Tatsujin. Ketsumeishi is a Japanese word for a type of medical herbs made from the seeds of Senna obtusifolia, which is often used for Chinese purgative medicines.

Най-добрите им песни според мен :
Ketsumeishi - Sakura
Ketsumeishi - Tomodachi
Ketsumeishi - Namida
Ketsumeishi - Natsu no omoide
Ketsumeishi - Sobani ite
Ketsumeishi - Motto
И много други техни песни, които можете да си свалите от тук

Нестандартна музика, малко непукисти си падат. Определено повечето от песните им имат послание и имат добра мелодичност и нелош ритъм. Клиповете им са свесстни, няма позьорство (типично за азиатските изпълнители). Определено любимци мои.
Ако ви харесват, можете да допълвате. Аз лично се учудих, като не намерих тема за Ketsumeishi.
