Song lyrics Sleepy Head by The Pillows

Kore wa risô janai
Nerau goal janai
Jibun rashiku monai
Iiya sô janai

Fukanzen na koi o shite
Shizu n de iku
Sleepy head
Futtobashitai

Tada no gisei janai
Karui game janai
Jibun rashiku monai
Sô janai

Fukenzen na kôi o shite
Sae wataru
Sleepy head
Futtobashitai

Mado no soto o miteru
Kareta niji o miteru
Niawanaku monai
Yes, i'm sleepy head

Fukanzen na koi o shite shizu n de iku
Fukenzen na kôi o shite sae wataru
This is my head
Futtobashitai
