My favorite thing about Napster and LimeWire was when you could find a song, and then BROWSE the hard drive of the person hosting that song. It was so interesting to find house music and be digging through the tastes of someone in London. And, then chatting with them, and discovering the live scenes, the people behind the music, etc. I loved that and nothing has ever replaced it.
Having said all this, I am interested in playing with "scrobbling." Anyone have any advice on how to get started? Do you need a music library? Is there a way to import your playlists from YouTube music? I'm not a spotify person.
