I couldn't believe it with my own ears...there it was. The unmistakable chords.

A mystery of that took 23 years, 3 months, and 29 days to be revealed. And probably the last main sample of MF DOOM that was unknown. To me, one of, if not, the GREATEST samples in hip hop / rap history.

The Musikos Music Library was active between 1990 and 1992 as a stock or library music for products, enhance business presentations, etc...

This also means that the 1970s porn lead was actually just MF messing with us... What a villain!

EDIT: with my excitement I made a typo ...I meant OFFICIALLY found.

EDIT 2: All credit to YouTube user @sdbsdb-me7pn who is NOT the person who uploaded the video today, who has an INCREDIBLE rare collection of music in his YouTube as he should be officially the person credited for the discovery.

He simply made a cryptic comment in my YouTube just saying "Musikos Music Library - 254-5", but that prompted me to investigate further and download the full music library album from the Library Music Themes music forum. And holy shit was he right...it WAS the sample.

EDIT 3: The full collection was assembled and uploaded to the Library Music Themes online music forum by GodzFire in January 2026 "as to not be lost to time".

In his post GodzFire said:

Collection of all known available music 25 albums from Musikos, the now defunct North Carolina-based production music library founded in 1990, published in Charlotte, NC.

A majority of the music was made by Neal Davenport, with some tracks made by Steve Dimond, Jamie Hoover, and William 'Bill' Soden.

The Musikos Music Library lasted until 1992 and was succeeded by the Davenport Music Library in 1993, with some of the Musikos Music Library tracks being carried over, but many not, including most of the William Soden Sports selections.
