"Most mysterious song on the internet" identified after 17 years — and the band was oblivious to the online phenomenon

For the last 17 years, a worldwide army of online sleuths obsessively tried to figure out the title of what has been dubbed "the most mysterious song on the internet." 

Now, they have the answer after a chance discovery by one intrepid researcher who triumphantly reported his breakthrough on online forum Reddit: it is called "Subways of Your Mind" and was recorded by a little-known 1980s German band called FEX.

The former band members are "absolutely overwhelmed" by the news, 68-year-old Michael Haedrich, who played keyboard and guitar and sang back-up vocals for FEX, told Der Spiegel magazine.
