HN users tend to prefer text first. Dropping personal playlists is a bit outside the usual discussions here, but the shared notebook concept is interesting. The design looks clean at least.
Thanks for the feedback. I understand that playlists are not the usual type of post here. The idea was more about seeing what people do with a shared notebook space rather than focusing on the music itself. It is just a small experiment to test how people use an open board when they can create their own section inside it. Glad you found the design clean. I tried to keep everything simple and fast.
