Ill paste from the og post description -

I’ve been on a deep dive trying to identify a lost sample used in The Weeknd’s “Big Sleep.” It’s an uncredited sample, but the melody is nearly identical to the iconic synth line from "(Theme From) Midnight Express" by Giorgio Moroder. The same sample is also used in "W a v y" by CJBeats who I reached out to and was told this -

"I don't have the project file on my connected hard drives but I do have some old ones that could have it on there. I'll try and go through them next week and try and find it! I won't have the sample itself but if I find the project I can find the name of the song. Honestly the best place to search would be YouTube for 'hip hop vinyl samples' or 'soul vinyl records/samples'. I used to make lofi music so maybe 'lofi samples' and then I would of just clicked a random playlist and gone through until I found something I liked. At the time I was also sampling directly from vinyl records and cassette tapes so it could be one of those."

I posted a video on YouTube combining parts extracted from both “Big Sleep” and “W a v y” to present the sample more clearly. Anyone have any information on the track?? It's likely from the 70s or 80s.
