《One》是美国女歌手斯凯·费雷拉演唱的一首流行电音舞曲，该单曲于2010年8月22日通过EMI百代唱片公司发行。

You don't know just how to start me up

Don't know how to get me going on

Something's wrong between the two of us

I'm not a robot but I feel like one

One two three four

Head to ground

I don't ever want the beat to stop

Speaking without a sound

You try to call me but you're breaking up

And all I can hear is one

And all I can hear is one

Don't know how to shut you off

Don't know how to keep this going on

I feel like I'm about to rust

Ruin my heart I'll buy another one

One two three four

Head to ground

I don't ever want the beat to stop

Speaking without a sound

You try to call me but you're breaking up

And all I can hear is...

I just want to hear your heart

Wake me up or I will keep my

Head to the ground

I don't ever want the beat to stop

Speaking without a sound

You try to call me but you're breaking up

And all I can hear is one.

音乐是由摄影师Rankin导演并于2010年6月2号公布在the Parlophone Youtube上。背景主要是Ferreira全身着红装在一个闪光的地板上的特写镜头，唱着进入到一个充满没有阴影的灯光的白色房间中，跳入到一份慢动作，并拉着白色的降落伞。

《One》于2010年8月29日打进英国单曲榜第64名。
