Overview

The VRM ListenLog is a proposed method for integrating simple user-driven functionality into an online audio player device or application. The ListenLog concept was devised in part for the Public Radio Tuner iPhone project, where it will likely be first introduced. The ListenLog is a consolidated and documented history of an individual's online listening activity. It is simply a recorded activity log, in a standard and open format, documenting an individual's listening actions through one (or more) online devices. The ListenLog is unique in that its aim is to give the user complete control over what to do with their listener activity data, including where the data lives, who to share it with, and how it can be used.

While tracking listener behavior is not a new concept, the ListenLog is a novel user-driven approach to deploying early VRM functionality. While a simple activity log might not be the killer app, it succeeds by putting in place a small piece of user-driven infrastructure into a larger application - one with a promise of relatively wide distribution. Since this infrastructure component will write, store, and share listener activity in an open and standard format, we hope that such a log will become significantly more useful as other devices and tools leverage the standard to increase what an individual can do with their ListenLog data. This type of sideways approach holds the promise of planting the seeds of VRM onto lots of devices without requiring the primary application functionality (i.e. audio listening) be purely user-driven.

A user-driven activity log works well for an application that pulls together audio streams and files from a number of different sources. Of course, online audio providers (vendors in the VRM model) can already track and aggregate listening behavior data, but only for the audio they control. When the user acts as the sole point of integration, pulling together audio from multiple sources, their own consolidated log becomes unique and powerful. Only when the listener is the point of integration does such an approach yield unique value.

ListenLog Specifics

Initially, the ListenLog will capture online audio stream and file listening behavior occurring through a specific application and device in a standard format. At minimum, the log will capture audio stream/file identification, user agent, listen start time, listen duration and device location information. Extending this data to incorporate unique device IDs, audio meta data, rating (e.g. thumbs-up/down), referral, or other application behavior data is a natural for consideration.

The application supporting ListenLog recording capability will host the minimum of user-facing functionality. Specifically, the individual user will be able to choose a digital identity(s) with which to associate their listening data, and can also choose where the data is stored, as it will be dynamically written by the device application to any ListenLog standards compliant service provider (host).

A separate ListenLog Service interface, perhaps integrated with the ListenLog storage provider, will enable the user to choose if and how to share their ListenLog data, either anonymously or as associated with digital identities. For example, an individual may choose to share all data publicly and anonymously. All users selecting this option would, in aggregate, create a single, public "firehose" feed of all listening activity. It is our hope that third-party developers will offer user-driven functionality based on your ListenLog functionality, helping you share selected data conditionally with vendors for example, or providing agnostic recommendations based on your listening habits.
