Radio The Way You Like It

A new streaming radio station in London attempts to gather data about what each listener likes and doesn’t like and tailor its music playlists. “Here’s how it works for Last.fm: Users can either fill out a profile or just begin listening. If a song plays to the end, the system logs this as a thumbs up. But if the user doesn’t like a song and hits the Change button in the Last.fm player, it’s marked as a thumbs down. Over time, a preference profile is built.”
