Playlisting
The Echo Nest is the leader in data-driven music playlisting. We leverage everything we know about music to
help music services deliver smarter, more personalized, highly interactive playlisting.
To meet the needs of all customers – from the largest digital music service providers to new music apps –
we provide three playlisting offerings: Basic for online radio, Standard for personalized, interactive music and
Premium for incredibly personalized, curated music discovery.
Basic Playlisting
Basic Playlisting, our entry-level playlisting offering, delivers simple and straightforward music playlisting or
radio stations based on a seed artist, song or genre.
Basic Playlisting API
The Basic Playlisting API supports artist seeds (up to five), song seeds (up to five) and genre seeds (up to five),
and returns a playlist of up to 100 tracks. Playlist results can adhere to the DMCA’s rules for non-interactive
webcasts.

3. music discovery & personalization
Standard Playlisting
Standard Playlisting delivers personalized playlists and radio experiences rooted in the most in-depth
understanding of each individual music fan. Standard Playlisting supports all playlist types in Basic, plus adds
the ability to create artist-specific playlists, personalized playlists, and tune any playlist or radio station on the fly.
Standard Playlisting APIs
Standard Playlisting utilizes one of two Playlist APIs, and may also be integrated with The Echo Nest’s Taste
Profile technology, which captures each fan’s unique music tastes and preferences to personalize playlists,
radio stations, recommendations, and other music discovery applications.
zz Static Playlist API - A simple “query-response”
API method, which generates a playlist of up
to 100 tracks based on the given artist(s),
song(s), genre, or Taste Profile.
zz Dynamic Playlist API - A suite of APIs that
deliver an interactive, personalized radio
experience that incorporates real-time feed-
back and tuning from the end user. Each
dynamic playlist session creates a new session
ID which maintains rules for playlist generation,
listening activity (plays, skips), and user feed-
back (bans, favorites, ratings) to ensure
continuity and an increasingly personalized
playlist experience.
zz Taste Profile API - Taste Profiles enable
customers to maintain a collection of artists
and songs associated with a specific user, as
well as that user’s listening activity and
preferences. Dynamic playlist session activity
(plays, skips) and feedback (bans, favorites,
ratings) can be recorded to a Taste Profile.
Unlike session IDs, which expire after 24 hours
of inactivity, Taste Profiles allow all listening
activity and feedback to inform future playlist
sessions.

Standard Playlist Filtering & Tuning Controls
Standard Playlisting includes a number of powerful filtering and tuning controls to allow users to personalize their
playlists, including:
zz Feedback - Allows user to skip, ban, favorite or
rate songs
zz Song Type - Include or exclude songs cat-
egorized as Christmas, acoustic, electric, live,
and studio.
zz Distribution - Determines whether playlists will
have a ‘focused’ distribution (tightly clustered
around seeds) or ‘wandering’ distribution (a
broader range of artists)
zz Variety - Controls the variety of artists that
appear in a playlist.
zz Adventurousness - Controls how much of the
playlist is known/unknown to the user based on
their Taste Profile.
zz Genre Presets - Three genre radio presets
-- Core, In_Rotation, and Emerging -- to power
unique genre discovery experiences.
Premium Playlisting
Premium Playlisting, our most advanced playlisting offering, leverages our deep cultural and acoustic
understanding of music, personal listener understanding, and an incredibly flexible engine to tune and
customize listening experiences. Premium Playlisting includes all Standard capabilities, adds additional playlist
controls, and supports the creation of user- or editorially-driven stations.
Premium Playlisting APIs
Premium Playlisting supports the same API methods and playlist types as Standard (Static Playlist API, Dynamic
Playlist API and Taste Profile API).

Social Discovery & Recommendations
Customers who use our Standard (Personalized) and

access to our new Social Discovery and Recommenda-
tions features as described below.
Social Discovery
Music fans love to discover new music from others who
share similar tastes. With our Taste Profile Similarity API,
music services can convert a user’s social graph into a
far more valuable ‘musical identity’ graph, adding
a layer of musical context across the end user’s social
network.
Recommendations
Music services can leverage Taste Profiles to gener-
ate personalized recommendations for each listener.
Marketers can use recommendations to steer users
towards content they are likely to enjoy based on insight
into listening history and relevant actions on the service.
