• 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.
