《Ecstasy》是倖田來未演唱的一首歌曲，詞曲由倖田來未完成創作，收錄於倖田來未的同名單曲EP中。
歌詞如下：
I feel the beat inside
Just like a thunder in my spine
And I don't know what it is
But I'm addicted to the danger
And I don't care if it's wrong or right
'Cause I want you tonight
I'm going crazy for it
It's a new sensation
It's ecstasy
So get on the floor and dance with me
Tonight we're gonna break the rules
And do what we want to do
So if you're ready to roll the dice
Come on and take a chance with me
The lights are low
And I can feel the shadows looming over me
The room is spinning out of control
I can taste the drugs in my soul
I'm in the zone
No way of pulling myself from this zone
It's a new sensation
It's ecstasy
So get on the floor and dance with me
Tonight we're gonna break the rules
And do what we want to do
So if you're ready to roll the dice
Come on and take a chance with me
Oh yeah, it's a rushin', euphoric feeling, yeah, yeah, yeah!
So get on the floor and dance with me, yeah! (oh yeah) (oh yeah) (oh yeah) (oh yeah)
