創作背景
關於主題曲
大谷智哉和道格拉斯·羅伯《索尼克：力量》的主題曲「Fist Bump」，意為“碰拳”。索尼克需要你（玩家自創角色）的力量，和他一起拯救世界。這將成為一個包含直觀信息的歌曲。因為這是《索尼克：力量》的主題曲，按照譜曲者大谷智哉的意思，是想給大家帶來一個新鮮的驚喜。為此，這首歌也不再採用諸如Crush 40之類的索尼克主要樂隊演唱，而是採用新的樂隊歌手演唱——也就是Hoobastank樂隊的歌手Douglas Robb。
發布與套用
feat. Douglas Robb from Hoobastank早在2017年3月，Yutaka Minobe就準備了這首歌的鋼琴版，由Koji Igarashi演奏。 無論是在Tag Team關卡，索尼克變身成超級索尼克，獲得無敵道具的經典索尼克，在最終關卡打蛋頭星球機器人，還是雙重加速（Double Boost）等這些都會套用到（除了雙重加速，其他都是純音樂形式）。 在遊戲的第一關失落山谷和手遊《索尼克力量：速度之戰》中的BGM雖然也有套用，不過風格和原版似乎有點差異。
歌曲歌詞
I can't do this alone
Even though I am strong
Need something more than me
Someone to push me to victory
Let's see what we can do
Together, me and you
Can't be afraid to try
Kiss your fears goodbye
No looking back
You and I, we're on the attack
Full speed ahead
Running to the sunset
Such a different feeling
Both of us believing
We can make it better
Together we can show the world what we can do
You are next to me and I'm next to you
Pushing on through until the battle's won
No one’s gonna give a thing to us
Into each other we put our trust
Standing united, after the fight
All alone, we will never be
The two, of us, are holding the key
We see, today, a world we couldn't see
Before I say goodbye to you
One more last fist bump...
I know you have been afraid before
But you don't have to be anymore
No more emptiness to feel inside
When we work together no one can break up our stride
No looking back
You and I, we're on the attack
Full speed ahead
Running to the sunset
Such a different feeling
Both of us believing
We can make it better
Together we can show the world what we can do
You are next to me and I'm next to you
Pushing on through until the battle's won
No one’s gonna give a thing to us
Into each other we put our trust
Standing united, after the fight is done
We can show the world what we can do
You are next to me and I'm next to you
Pushing on through until the battle's won
No one’s gonna give a thing to us
Into each other we put our trust
Standing united, after the fight
It's a brand new day
We have turned the page
I never knew how much I needed
Somebody to help me this way
All alone, we will never be
The two, of us, are holding the key
We see, today, a world we couldn't see
Before I say goodbye to you
One more last fist bump...
