Aa, Subarashiki Nyan-sei (Ah, It's a Wonderful Cat Life)

The song 'Aa, Subarashiki Nyan-sei (Ah, It's a Wonderful Cat Life)' by VOCALOID, featuring the voices of Len and GUMI, is a whimsical yet profound dialogue between two cats with contrasting lifestyles. Len, the stray cat, represents freedom and adventure, while GUMI, the domesticated cat, embodies comfort and security. Through their conversation, the song explores themes of freedom, security, and the choices that define our lives.

Len's verses are filled with the allure of a carefree life. He invites GUMI to break free from her collar and join him in a world where they can chase birds, eat fish, and dream on rooftops. His perspective is that life is short ('nyan-sei wa ichido kiri'), and it should be enjoyed to the fullest. Len's life is one of spontaneity and excitement, unbound by the constraints of human society.

On the other hand, GUMI's verses highlight the benefits of a domesticated life. She enjoys delicious meals, a cozy bed, and the safety of a home. GUMI acknowledges the value of her branded collar and the security it provides. She questions Len's ability to understand the worth of her lifestyle and points out the dangers he faces as a stray. Despite her admiration for Len's adventurous spirit, she remains committed to her current life, partly out of responsibility to the girl who owns her.

The song culminates in a bittersweet realization that their dreams and lifestyles are incompatible. Len dreams of traveling to the northern country to see the aurora, a dream he wishes GUMI could share. However, GUMI's sense of duty and the comfort of her current life prevent her from joining him. Their conversation ends on a hopeful note, with GUMI inviting Len to visit her again, suggesting that while their lives may be different, their friendship can still endure.
