I have a specific order to obtaining my favorite vgm:
1 - Buy / Download from the artist legit if available, whether from bandcamp or as dlc for some games
2 - Check to see if sittingonclouds.net or sephi.zophar.net have it
3 - Check if it’s on spotify & use spotiflyer if so
4 - Last resort if it’s only on youtube or soundcloud… yt-dlp
Now that I wrote this I probably should have asked if you stream or download music but whatever.
I’d never heard of soulseek before but it looks like a really neat piece of software! I’ll have to check that out at some point.
