"Thoughts" is the seventeenth single by Japanese rock band Luna Sea, released on August 28, 2013. It reached number 7 on the Oricon chart and number 14 on Billboards Japan Hot 100.[1] [2]
The B-side "Lost World" is one of the few Luna Sea songs originally composed by Ryuichi. Inoran said that Sugizo helped arrange it and thus added his own "essence" into it.[3]
The single was released in three editions; a regular CD single, and two limited editions both with the music video for "Thoughts", but one version with it on Blu-ray, the other on DVD.[4] All three have different cover art.
"Thoughts" was used in a commercial for the mobile game Master of Chaos,[4] while "Lost World" was used in one for the game Space Fighter.
All songs written and composed by Luna Sea.
