Each dictionary will have the following keys:

• title: Name of the song search result in YouTube, used for naming the corresponding wav file.
• query: An HTML encoded version of the original song title and used as a query parameter.
• chromagram: The song's chromagram in linear time.
• beat_chromagram: The song's chromagram in beat time.
• id: The song's youtube id.
• annotations: The song's annotations. Contains the contents of its corresponding annotation file in one string.

The beatles dataset was not added in this repository because of copyright issues.
