Robo's Theme
"Robo's Theme" is a track composed by Yasunori Mitsuda for the game Chrono Trigger. It is the second track on the second disk from the original soundtrack. The track first appears after Lucca successfully repairs Robo for the first time.
The song has similarities to a popular J-pop dance song, TRF's "EZ Do Dance" (1993), which has a similar melody and chord progression about one-and-a-half minutes into the song. Mitsuda was likely inspired by "EZ Do Dance" as it was a major chart-topping J-pop dance hit in Japan.
In the West, "Robo's Theme" is often compared to Rick Astley's hit song "Never Gonna Give You Up" (1987), as there are some similarities, notably the Yamaha DX7 bassline. In turn, "Never Gonna Give You Up" was itself heavily inspired by an earlier Colonel Abrams hit song, "Trapped" (1985), including the DX7 bassline. When asked about the "Never Gonna Give You Up" similarities in an interview, Yasunori Mitsuda stated that he had never before heard of Rick Astley or his music. This is due to "Never Gonna Give You Up" never charting in Japan. It's possible the earlier Colonel Abrams song "Trapped" may have been an influence on the "Robo's Theme" bassline, but "Trapped" never charted in Japan either.
