> Are 2000 winamp and 2022 spotify app comparable?
In my opinion - yes. Most of what Spotify provides implemented in the cloud (on server side). Client is a UI to select and stream music. Winamp supported music streaming to but didn't have an advanced UI to select what to stream. I see no fundamental reasons why a desktop app for Spotify should use much more resources. Given open API it should be possible to make a Spotify plugin for Winamp.
I haven't used Spotify desktop app but can guess it is written using electron or something like that and this is the main reason it uses much more RAM/CPU than Winamp, not because it does more work.
