No lurking, no endless algorithmic feed, just the people you know and the music they're into that week. What you can do: - Post a new four-song lineup every week - See your friends' weekly lineups in a shared feed - Build a profile with a timeline of your past lineups and your all-time favorites - Like and comment on lineups through the week - Find and add friends - Connect Spotify or Apple Music to pull in song suggestions while you build - Get notified when friends like or comment
