Wow, this is the first I've heard of scrobble.life, I just checked it out. Such a cool idea, especially if we were able to write reviews directly on the site.

I was floating around and on the music tab it has a live section where it said you were listening to Metallica, that's an interesting idea. People being able to click on what someone else is currently listening to, to listen themselves.

Expanding on that idea, it would be cool if we were able to set up a playlist, and do a talking livestream/ radio show. It would be a good way of hanging out and chatting with people.
