Translation of the song lyrics Happy Birthday - Shikao Suga

Happy Birthday (original)

うまく話ができなくて 本当は すまないと思ってる
しばらく 悩んでもみたけど そのうち 疲れて眠ってる
週末のこの街の空気は 人いきれでむせかえり
深くため息をついたら 街頭スピーカーに 消された
それらしい言葉を ならべても
伝わることなど はじめからない
※にぎやかな この街の空に
おもいきり はりあげた声は
ぼくに 優しくしてくれた
あの人への Happy Birthday※
何か小さなトラブルで 人だかりにのみこまれ
誰かの つまらないジョークに ほんの少しだけ笑った
いつか この街のどこかで 君と偶然出会っても
何を話したらいいのか いまでも よくわからない
ひとつずつ こわれてゆく世界で
流した涙に なんの意味がある
にぎやかな この街の空に
おもいきり はりあげた声は
どこか遠くの街にいる
あの人への Happy Birthday
Uh…
(※くり返し)

Happy Birthday (translation)

I'm really sorry I can't talk well
I've been worried for a while, but she's tired and sleeping
The air in this city on the weekends is crowded
When I sighed deeply, it was erased by the street speaker
Even if she arranges such words
There is no such thing as being transmitted
* In the lively sky of this city
The voice that she raised
Kind to me
Happy Birthday to that person *
Swallowed by a crowd due to some minor trouble
Someone's girlfriend laughed a little at a boring joke
Even if she happens to meet you somewhere in this city someday
She still doesn't know what to say
One by one she is in a breaking world
What does she mean by the tears shed?
In the bustling sky of this city
The voice that was raised
I'm in a city somewhere far away
Happy Birthday to that person
Uh ...
(* Repeat)
