Given this context, surely the article should at least mention http://www.freedb.org/ or https://musicbrainz.org/ ?
Edit: Added musicbrainz
What gives me hope though is that two databases you mentioned are freely-licensed and do provide data dumps. This is essential for programmers to be able to create things that rely on these databases. We need to establish more free data stores, because as the article mentions, data is very valuable, and as the Wikipedia links show, proprietary databases have absolute control over their terms, restricting and locking out competition at any time.
