それはただの気分さ (romanized: Sorewa Tadano Kibun Sa, English: It's Just a Feeling) is a song by Japanese rock group Fishmans, written by Shinji Sato. It was recorded sometime in 1997, around the time the band's seventh studio album 宇宙 日本 世田谷 was recorded, and was originally meant to be a song for J-pop group SMAP. It appeared on the latter's album SMAP 011 ス released in the same year. It's assumed the song was originally discarded from the album. A complete demo of the song was released on Aloha Polydor in 1999. More notably, an 18-minute long version of the track was performed live on Space Shower TV on January 11, 1998 @Space Shower TV. A studio recording of the song was never physically distributed until after Sato's death.
At the end of the night, sit down at the summit
Tell me your story in a weak voice
Ah-
Have I ever forgotten your thoughts
I'm tired of everyone's sorrowful favors
I want to see your most tired face
I want to be near your face that you don’t wants to see anyone
It's just a feeling, it's just a thought
It's just a feeling, it's just a thought
