"Day by Day" 是銀魂中一首常用的歌曲，以下是一些基本的歌詞：
Day by day, day by day
Just keep on going, going on
Day by day, day by day
Life's a journey, gotta ride the wave
Keep your head up, keep your feet on the ground
Take it one step at a time, you'll be alright
Day by day, day by day
Gonna make it happen, make a change
Day by day, day by day
Life's a journey, gotta ride the wave
Through the highs and lows, the laughter and the tears
Never giving up, never looking back
Just keep on pushing forward, day by day
(Chorus)
You may stumble and fall, but don't give up the fight
Pick yourself up, dust yourself off, and start again
Day by day, you'll get stronger
Day by day, you'll be a star
(Verse 2)
Through the mountains and valleys, you'll find your way
With every challenge, you'll rise up and face it again
Day by day, you'll learn more
Day by day, you'll find your passion
(Chorus) (repeat)
