Not an amateur producer at all, but a few years ago I was listening to a lot of YouTube mixes while working. Lofi stuff might be cookie cutter elevator music to you, but I loved some mixes over others. I got attached to some of them, and discovered a ton of artists that way. These were single, long videos with many tracks each.
My heart sank when I started finding some of them turn into broken links. I figured out YouTube-DL and got to archiving. I found some reuploads of playlists I liked such as the wonderful Morning Coffee by the amazing SoulSearchAndDestroy (the lead song, damn fine coffee by mtbrd, is one of my favorite lofi tracks ever). Other playlists have been lost to time.
Sometimes I skim through my archived playlists to find a song I can remember in my head, and sometimes I don’t find the song, and it’s possible that I will never find it again. Again, silly for this to happen with lofi of all things (one of the most dispassionate and almost disposable genres of music).
I still think YouTube is unmatched for music discovery. Yes, you’re clicking on songs for “bad” reasons such as the thumbnail or recognizing the curator’s channel, but it worked pretty damn well for me.
