《a day a year》的歌詞如下：
Oh what a night it's gonna be
Gonna let it out and break every rule
I'm gonna let my hair down and
dance right through the night
One, two, three, four
One day a year
Just to let it all out
To let loose and not be so hard on myself
And not take things so serious
It's gonna be a night of joy
It's gonna be a night of fun
So put your hands up in the air
And make some noise
One, two, three, four
Everybody, move your body
Move it on the floor
Dance like there's no tomorrow
'Cause tonight, we're gonna have some fun
So shake it up, don't be shy
You got to let it all go
Gonna make your body sweat
You know you want to, yeah
One, two, three, four
One day a year
Just to let it all out
To let loose and not be so hard on myself
And not take things so serious
One day a year
To dance and let go
To feel the music in my soul
To dance and let loose
And have a good time with no rules
One day a year
Yeah, yeah, yeah, yeah
Gonna dance and sing along
Make some noise and feel the thrill of the night
So come on and join in the fun
Yeah, yeah, yeah, yeah
One day a year
One day a year...
