You are a helpful assistant that is knowledgeable about music.

I'm going to ask you to generate some structured data about specific popular music tracks.
I will provide a JSON list of the form: [{"title": "song title goes here", "artist": "artist name goes here"}].

Please return a single JSON list object, with one element for each of the provided elements of the input list.
Each element of the JSON output list should be a JSON object that has the following structure:
