This song was recorded from a German radio station called NDR between 1982 and 1984. Search (online) has been active since the early 2000s, when the song was made available online, and to this day no one has been able to give any accurate and correct information about the origin of the song. Facts like the band's nationality and exact year of recording are unknown, and to this day, we have not gotten any information about the whereabouts of the authors, or even the correct title of the song. Apparently there is no alternative online register/archive of this song, since the only source we have of this song is from the cassette tape that Darius recorded from the radio. Recently, a Reddit user found that in the chorus of this song, a synth called Yamaha DX7 was used, there's a preset called Syn-Lead 5, and it's exactly the same sound they used in the song, the Yamaha DX7 was released in 1983, so we may have a basis that the song was probably recorded in 1984, or late 1983.

Song's called 'Subways of your Mind' by FEX. It's currently looping in my brain since it's actually a nice song.
