The song known online as “The Most Mysterious Song on the Internet” is “Subways of Your Mind” by FEX, a German band. Its identification in November 2024 ended a 17-year search—and showed how a scattered community turned an obscure radio recording into a solvable research problem.
What was the most mysterious song on the internet?
The track was recorded from a German NDR radio broadcast in the early 1980s by a teenager, then circulated online from 2007 without an identified artist or title. Searchers gave it several nicknames, most famously “The Most Mysterious Song on the Internet,” or TMMS. WIRED recounts that the recording was identified in November 2024 as “Subways of Your Mind,” performed by FEX. WIRED’s account of the search describes the 17 years between online circulation and identification; NDR’s reporting independently connects the song to the band and a 1983 recording.
How did researchers identify the song?
A possible route through Hörfest
The search reached across YouTube, Reddit, Discord, and music forums. A particularly useful lead was Hörfest, an NDR-associated contest for amateur bands. The researchers found extensive local-government archive material and used it to narrow the field to obscure regional acts that might not appear in ordinary online searches.
Arne, a moderator of the r/TheMysteriousSong subreddit who posts as LordElend, told WIRED: “We realized that 800 bands, most obscure and not on Google, will need a larger group of researchers.” That figure was his estimate of the bands to investigate through the archive material, not an independently audited count of all acts searched. Dividing the work made a large, fragmented set of records more manageable.

Connecting a name to FEX
In WIRED’s account, a researcher connected an individual appearing in community band lists to FEX through another band, Phret. Contact with former FEX members then confirmed the identification. The breakthrough depended not on one definitive database, but on combining archival clues, community-maintained information, and direct confirmation from the musicians.
Why the circulating recording was not the whole story
The online copy came from an NDR broadcast, but it was not the only surviving source. NDR later reported the recovery of an original recording and noted a difference in the audio: the 10-kilohertz dip heard in the internet version was absent from the recovered source. That detail helps explain why copies could sound different; it does not change the identification of the song.
Rank #2
It is also important to distinguish the original NDR/TMMS recording from later recordings and releases. The recording that launched the search was not simply interchangeable with the band’s subsequent versions.
What happened to FEX after the discovery?
The identification revived attention to the band and its music. NDR reported in December 2024 that FEX had reunited to record the song again; band member Michael Hädrich described the worldwide attention as overwhelming. Official releases followed, including a 7-inch single and a release featuring the original TMMS version.

The 7-inch single and its digital masters
FEX’s official Bandcamp page documents the December 2024 7-inch release, “Subways Of Your Mind (Like The Wind),” backed with “Heart In Danger.” The page credits the composition to Ture Rückwardt and Michael Hädrich and the lyrics to Rückwardt. It says the vinyl retains an earlier master than the later-improved digital masters. FEX’s release page has the edition details.
The original TMMS version
A separate official vinyl release presents the remastered original TMMS version—the version played on NDR in the mid-1980s, according to the release page. FEX states that the digital master was replaced on November 4, 2025 with a transfer from a better-sounding cassette, while the vinyl continues to use the first remaster. Because release pages can change, check the current listing if you are choosing a particular version. The original-version release page describes its master and formats.

The case became more than a hunt for a song title. It let people contribute different kinds of work—finding archival records, comparing clues, and following leads—without needing to be part of a formal institution. Josh Chapdelaine, a media studies professor at Queens College, told WIRED: “They provide people a chance to contribute to investigations that anyone with a critical approach can advance.”
“Lostwave” is a broader term for unidentified pre-internet music; TMMS was one especially visible search within that category. Its resolution demonstrates a practical lesson: when records are scattered and the likely artists are obscure, a community can make progress by dividing research and then verifying its strongest leads with people who were there.
