LlamaIndex Readers Integration: Genius

This loader connects to the Genius API and loads lyrics, metadata, and album art into Documents.

As a prerequisite, you will need to register with Genius API and create an app in order to get a client_id and a client_secret. You should then set a redirect_uri for the app. The redirect_uri does not need to be functional. You should then generate an access token as an instantiator for the GeniusReader.

Usage

Here's an example usage of the GeniusReader. It will retrieve songs that match specific lyrics. Acceptable arguments are lyrics (str): The lyric snippet you're looking for and will return List[Document]: A list of documents containing songs with those lyrics.
