A: An algorithm for a great music experience

Q: What is a Playlist?

What’s a Algorithm?

An algorithm is: A step-by-step set of instructions for calculating something.

A recipe can be an algorithm

In the case of Last.fm’s personalized radio stations, our algorithms are designed to create a string of song recommendations based on a listener’s musical history

Making a great algorithm is hard work

How we feed the algorithm: Information about who is listening & what they love

Last.fm Personalized Radio Playlist

Context + Meaning

In the world of personalized internet radio, Last.fm has the best playlists

…But I think we can make them better using a hybrid of computer

power and human skills.

why I’m here today

WHAT WOULD JOHN PEEL DO?

The best DJs provide context & meaning to what they play

They bring certain elements that computers can’t match

• An compassionate understanding of their audience• Deep love and esoteric knowledge of the genres they play• A lyric sense of the syntax of a great playlist

Tips for surviving a hybrid world

.

1. Algorithmic playlists and personal listening data from smart phones and computers are here to stay….but they don’t replace individual voices and personality in radio. Put both elements in the mix.

2. Traditional radio’s limited playlists are not the full set of songs that your audience listens to or have access to anymore. Admit this and make suggestions for artists and things off your line, particularly online. Give them directions to explore new artists, off-list.

3. Your audience expects their playlists to be interactive and they are looking for ways to add personal context to on-air playlists. Use the space in radioplayer.co.uk, your forums, social media channels to encourage their contributions…. and they will amplify your playlists with their data and desires.

Have some science with your art. It will make your art better.
