WINTER参与作词、作曲的SOLO曲《Spark》是一首蕴含着既梦幻又惆怅感性的清爽EDM声效令人印象深刻的歌曲，歌词用隐喻表达了仅凭一个微小的火苗便陷入炽热之爱的感情。

Woo-Ha
Whoo
Light up your heart
So I can see you shining
Say what you see
Try feeling me wherever you go
Connect to my heart
I want you to learn
Every little thing about our love
Illuminate the night
Breathe into my soul
Hoo
One little Spark is all I need
A fire burning for something new
One little Spark and you set me free
Now one becomes two
Only takes one little Spark
And we're igniting
Come light it up
Now when the sun goes down
I'm never in the dark
Like a candle you're burning bright
You talk like honey
How you so sweetly reassure
One little Spark is all I need
A fire burning for something new
One little Spark and you set me free
Now one becomes two
Only takes one little Spark
And we're igniting
Come light it up
넌 이끌린 대로
더 가까이 와
날 느낄 수 있게
Feel the Spark with me
It will never be dark
