A ride on the subway drastically changed Tokyo band Moscow Club's fate. After the quartet used crowdfunding site Indiegogo to finance its first full-length album, the members felt it was a good point to end a project that had transformed from a hobby into something taxing.

"We just left it after that. We didn't do anything," the group's lead singer and synthesizer player Kazuro Matsubara says. "But we realized, if we didn't do anything, this Moscow Club experience would just fade away."

Then Matsubara found himself on the Tokyo Metro. While waiting at Tameike-Sanno Station in February 2014, he heard the stop's melody and was inspired to write "Celine," a twinkling song packed with a sense of romantic longing.
