《couldn't be better》的歌詞如下：
I feel so amazing
Gonna make you dance the night away
Everybody look at my way
Can't be wrong
Gonna take this chance for my own
Going out of my way
To get what I want and that's you
Can't stop, won't stop
Gonna get it tonight
Everybody get up and dance now
Feel the rhythm, let the music take you higher
Yeah, I got it, can't you see it
We can't be beat, it's in the air, feeling stronger
No time for dreaming
There's so much we can do, tonight, yeah
This is our time
Come on, take it higher, won't stop until the sun rise.
歌曲中反覆地高歌：我能做更好。在這個世界沒有我做不到的事。我知道你能聽到我心裡的聲音，雖然路途有些坎坷，但是不會讓我停止向前，一切都是值得的。表達了無畏無懼、一往無前的積極態度和信念。
