In an interview with The Wall Street Journal, LCD Soundsystem’s James Murphy expressed his desire to soundtrack the New York City subway system. Murphy says he has been working on the project for the past 15 years, creating a unique set of notes for each of New York’s 468 subway stations.

Now, with the MTA about to embark on a $900,000-a-year project to improve passenger flow at some stations, Murphy believes this is his opportunity to re-introduce his plan. However, MTA spokesman Adam Lisberg told the WSJ that while Murphy’s plan is a “very cool idea,” it would likely require a lot of time and money and could also require taking each of the city’s 3,289 turnstiles out of service. A risk Lisberg says the authority is not inclined to do “for an art project.”

To create more buzz about this potential venture, Murphy created a petition entitled Subway Symphony, where he explains his plan and closes with, “Please help me make our city just a little more kind.”
