sing a long song

為了延續方大同上一張專輯《未來》中《Love Song》一曲的概念，為心愛的人寫歌，並且將思念之情透過歌曲得以傳達，方大同繼而創作了該曲。因為方大同交出的原創DEMO時就已經很完整，而且越聽越有味道。所以唱片公司決定，將該曲作為音樂專輯《橙月》的開場曲饗以歌迷 ^[2]  。

I wrote this song

It's not too long

Cos I've been thinking 'bout you

I wrote this song

Maybe I'm wrong

To be caught up about you

Well I don't know what you think about me

Maybe you think nothing at all

But maybe you could just lie to me

And we could be in love, you see

Oh it's a singalong song that's not too long

It's when I think about you that I hear songs

And you can sing along

Maybe if you want to

Cos baby I wrote this,I wrote this for you

I wrote this song

It's not too long

Cos I'm the one who loves you

I wrote this song

This can't be wrong

I don't wanna smile without you

Well I just want to make you happy

But maybe you want nothing at all

And how I wish that you're meant to be

Forever and a day with me

Oh it's a singalong song that's not too long

It's when I think about you that I hear songs

And you can sing along

Maybe if you want to

Cos baby I wrote this,I wrote this for you

In everyway, you mean more to me

Than you’ll ever know

Girl, I'll do my best to show these words are true

And if you'd like to make a song

And be a perfect harmony with me

I'd find the greatest words to sing

So we could write our own romance

Oh,it's a singalong song that not too long

It's when I think about you that I hear songs

And you can sing along

Maybe if you want to

Cos baby I wrote this,I wrote this for you

Oh it's a singalong song that's not too long

It's when I think about you that I hear songs

And you can sing a long

Maybe if you want to

Cos baby I wrote this,I wrote this for you ^[3] 

《sing a long song》中，方大同依舊保持着獨特的“騷靈音樂”風格，傳遞着簡簡單單的情緒，或者快樂，或者哀傷 ^[4]  。這首復古作品，可以看做是他向偶像Stevie Wonder的致敬曲目 ^[5]  ，方大同用動聽的嗓音和自成一派的風格打動聽眾 ^[6]  ，他的語氣清淡卻不失誠懇，流暢的旋律勾起聽眾主動循環的慾望，讓人在潛意識被它催眠 ^[7]  。
