Unpredictable

該單曲延續國際首席團隊傾力打造的風格，聯手美國製作人David Gamson及詞作者Dave Gibson，並由兩位音樂大師聯合譜曲。易烊千璽在聽到該曲的小樣後，覺得旋律特別好聽，歌詞也很貼合他的心境，所以只用了一個下午就錄完了。而且這首歌的旋律和歌詞一次都沒有改過，就是原版的小樣。易烊千璽在錄音的時候想着，未來也許很迷茫很不確定，所以要一步一步邁好腳步，副歌最後一句，‘I live a life，Unpredictable’（我要的未來，無法預測），易烊千璽認為這句歌詞跟他的生活很接近。 ^[3-4] 

Little bones little coloured stones

Try to keep try to keep you warm

If you wanna know wanna know your mind

Leave it all leave it all behind

There are things that are better left alone

So many questions out of your control

I don't wanna know how this is gonna end

Coz it won't stop the rain from coming down again

And I don't need that superstition fortune telling future magical

I live a life unpredictable

I live a life unpredictable

Little leaves little leaves will form

Try to see try to see the storm

If you wanna know wanna know your heart

Lose it all lose it from the start

There are things that are better left alone

So many questions out of your control

I don't wanna know how this is gonna end

Coz it won't stop the rain from coming down again

And I don't need that superstition fortune telling future magical

I live a life unpredictable

I live a life unpredictable

Unpredictable

Unpredictable

Unpredictable

Unpredictable

I don't wanna know how this is gonna end

Coz it won't stop the rain from coming down again

I don't wanna know how this is gonna end

Coz it won't stop the rain from coming down again

And I don't need that superstition fortune telling future magical

I live a life unpredictable

I live a life unpredictable ^[1] 

《Unpredictable》旋律舒緩優美，反覆迴旋中帶給人以空靈寧靜之感。易烊千璽磁性柔和的嗓音，低吟淺唱“I live a life, unpredictable.”淡淡的憂傷與年輕無慮的精神內核相融，詮釋了當下大多數人的心理狀態，與其預測着看不見的未來，不如拋下顧慮和枷鎖，肆意生長。未可知的一切，皆是精彩的開場。 ^[4]
