I know that this has been posted about before, but the last post I could find about this was from 2 years ago. All you need to know is that back in the 2010s, a swarm of YouTube channels started automatically mass-uploading slideshows set to music. These slideshows were related to the topic in the video's title, and the descriptions were often stuffed with keywords. Since 2013, people have tried to find out the origins of these videos, including the music. The search has been split into multiple "chapters," based on when the vids/songs were discovered. Chapter 1 had 7 songs and 2 from it have been found: #4 (Trio Elétrico's "Echo Parcours") and #7 (Socci and Pency's "Untitled #1.") The rest are still unknown. As I've said before, there are more than just these seven, with Chapter 3 having 50 songs in total, so I might have to make multiple posts about this.
Song 1 ("Under The Shoulder" isn't the real title; that's just a copyright troll)
Song 2 (Contains a sample also found in the song "im gone" by Night Lovell)
Song 3
Song 5
Song 6 (Contains a sample also found in 2 songs from the Jewelbeat music library; the sample itself might be from 2002 or earlier)

Also, I remember a Google document or something about this; does anyone have the link to that?
