憂鬱 means "melancholy" or "gloom," describing a deep, lingering sadness rather than a brief moment of feeling down. In the song, it appears in the poetic image 憂鬱が空を覆い尽くしたって ("even if melancholy covers the sky"), making the emotion feel vast and atmospheric while the singer continues to believe in the future.
A short love song sung to someone who is crying. The singer opens with "泣かないで 愛しい人よ" (don't cry, my darling) and admits the city around them feels cold: "この街が僕らを孤独にするのなら" (if this city is making us lonely), then the answer is to keep dreaming together and "この風に身を委ねて踊ればいい" (just give yourself to this wind and dance).
The bad weather never fully lifts. Gloom covers the sky and the rain has no end in sight, yet the singer says "未来を愛していられる" (I can keep loving the future) because "あなたとなら季節が巡り始める" (with you, the seasons start turning again). The title line, "時計の針を進めて" (move the hands of the clock forward), asks time to keep going rather than stopping it. The second verse walks through a whole year in one breath, spring breeze, summer smell, the snow falling again, and ends on a plain invitation: "一緒に踊らないかい?" (won't you dance with me?).
