"Day by Day" 是日本樂隊彩虹樂隊的歌曲，其羅馬歌詞如下：
Day by day, I'm getting stronger
Trying my best, not wanting to fall back
Try and win it all today
Can't wait to let you know, feeling higher now
Day by day, never been feeling stronger
Get on my feet, stand tall
All alone, can't deny the power
Can't stop me now, on my way to reach the sky
Let it be right now, go on your own
Life's so short, it flies away
Why wait till tomorrow, we don't have a time to lose
Let's start today, I'm gonna win
Day by day, I'm getting stronger
Trying my best, not wanting to fall back
Try and win it all today
Can't wait to let you know, feeling higher now
Day by day, never been feeling stronger
Get on my feet, stand tall
All alone, can't deny the power
Can't stop me now, on my way to reach the sky
Oh yeah, you know that I'm feeling it all
You know that I'm feeling it all
Oh yeah, you know that I'm feeling it all
Oh yeah, I'm gonna make it now
Day by day, I'm getting closer
Gonna make it now, gonna make it now
Day by day, I'm gonna win it all
Gonna make it now, gonna make it now now
Oh yeah...
