About Music Time Machine
An independent, year-centered listening atlas comparing four music cultures without pretending they share one universal soundtrack.
Purpose
Music Time Machine organizes listening windows from 1970 to 2022 across Korea, the US and UK, Japan, and Brazil. It is an editorial discovery tool, not an official chart or a complete history of world music.
Editorial responsibility
The Music Time Machine editorial team selects catalog references, reviews corrections, handles rights requests, and makes privacy decisions. Commercial placement does not determine selection.
OPTIWORK’s role
OPTIWORK designed and developed this website. OPTIWORK is not the service operator, publisher, or data controller unless a specific activity is separately identified.
Contact
