VRM ListenLog

Keith Hopper outlines his vision for ListenLog as an example (and element?) of future VRM solutions:

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.
