The dataset contains the analysis and metadata for a million songs. The goal is to provide a large dataset for researchers to report results on, hence encouraging algorithms that scale to commercial sizes.
Most of the information is provided by The Echo Nest. The dataset is the result of a collaboration between The Echo Nest and LabROSA at Columbia University. This project is funded in part by the NSF.
Most of the data is licensed the same way as Echo Nest's API.
