歌曲背景
《Wonderful U》是江海迦2016年發行的歌曲，也是同專輯中歌曲《圓》的英文版。在《天賜的聲音4》中，薛凱琪和Jessica選擇合唱這首歌，為了更好地傳達歌曲的情緒，兩位音樂人還向原唱AGA江海迦「取經」，了解歌曲背後的故事。但在臨近演出前，兩人紛紛病倒、失聲，不過最終還是為觀眾帶來了精彩的表演。
歌詞含義
歌曲講述了一個情竇初開的女生，幻想着和自己青梅竹馬的好友墜入愛河的故事。歌詞如「I never knew when the clock stopped and I’m looking at you. I never thought I’ll miss someone like you」，描繪了女主在凝視對方時仿佛時間停止，從未想過會如此想念對方的情景，體現了對對方的深深眷戀。「Baby you know that I’m so into you. More than I know I should do」則表達了女主知道自己過於投入這份感情，甚至超出了應有的程度。「But I know that it’s wonderful. Incredible baby irrational」等歌詞，既展現了這份感情帶來的美好、不可思議以及讓人失去理智的感覺，又透露出一種無奈和悲傷，如「Even now I just cannot feel you feel me」，表示即使現在也感覺不到對方對自己的感情，整體傳達了一種將美好感情埋藏在心裡的複雜情感。

I never knew
When the clock stopped and I’m looking at you
I never thought I’ll miss someone like you
Someone I thought that I knew
I never knew
I should have known something wouldn’t be true
Baby you know that I’m so into you
More than I know I should do
So why why why
Why should we wait there
And I I I
I should be waiting
Waiting for someone new
Even though that it wasn’t you
But I know that it’s wonderful
Incredible baby irrational
I never knew it was obsessional
And I never knew it was with you
Baby if it’s just wonderful
Incredible baby irrational
I never knew it was so sad
Just so sad I’m so sorry
Even now I just cannot feel you feel me
Why why why
Why should we wait there
And I I I
I should be waiting
Waiting for someone new
Even though that it wasn’t you
But I know that it’s wonderful
Incredible baby irrational
I never knew it was obsessional
And I never knew it was with you
Baby if it’s just wonderful
Incredible baby irrational
I never knew it was so sad
Just so sad I’m so sorry
Even now I just cannot feel you fall
I don’t even know now if you wait for me
Even now I just cannot deny
I just hold on so tight
Until you and I never could breathe
Wonderful Incredible baby irrational
I never knew it was obsessional
And I never knew it was with you until you tell me to
Baby if it’s just wonderful
Incredible baby irrational
I never knew it was so sad
Just so sad I’m so sorry
Even now I just cannot feel you feel me
