In addition to the usage of music by famous bands the show is known for, MTV's Daria also used a fair amount of production music throughout its run.
There are around 25 that remain unidentified, with one of them having been noticed as far back as 2005. Not a single music recognition program (Shazam, SoundHound, a-ha music, etc.) can recognize any of them. None of them are on any list of songs for the show either.
All of the production tracks that have been identified so far were distributed by APM Music in the US during the show's production. However, considering that music published by APM is in at least one music recognition database, I doubt these unidentified tracks were distributed by them.
Almost all of the music, including production tracks, were removed from the DVD/streaming release.
Here is a video containing 12 of the clearer unidentified tracks:
Clips 1 to 4 are from 1997, clips 5 and 6 are from 1999, and clips 7 to 13 are from 2001.
If anyone knows where even one of these is from, please leave a reply.
Thanks for reading.
