Hey, thanks for the question!

The main difference & significant improvement that our technology provides is its ability to not only extract high-level data (e.g. emotions, tags) from music (Echonest, for example, primarily emphasizes low-level attributes like beats, tempo, etc.), but also perform other important operations over this data (like querying by moods/tags, finding similar tracks, search by natural language, etc.).

So, in a way, our technology acts as an actionable intelligence layer over music, as opposed to just extracting & returning low-level data.

And yes, you could give it new songs & get back the extracted metadata. Plus, our commercial users can also integrate their own music catalog with our technology.

Thanks for the question! :)
