Thanks for such a detailed review! 

Most of the samples are actually royalty free/public domain single pieces or sample packs from the internet processed afterwards to a different extent, except for some melodies I wrote myself (although some melodic pieces are also samples + I used a ~century old melody once ). I think in S0M3NO1ZZZ3 I used mostly thingies from EDMProd starter kit? And for the long number track (it has a palatable name but I'd like people to figure the cipher out, it's a simple data conversion) I used 0 copyright filter on Freesound iirc, basically I was searching the pieces by bpm and selecting what I like, there are surprisingly a lot of public domain samples (or sometimes even full songs??)  that sound so fire it's amazing. SampleFocus is also ok and even first page in google level sites like Pixabay can work sometimes. The vocals are made in TTS called Speech Note (it's for Linux idk about other systems, it uses stuff like espeak-ng maybe you can look for that), and I played around with some plugins and settings in FL after the recording.
