Thanks. I'd imagine an API is on the cards, but I could be wrong. As far as I can see, beyond the website, their data has two markets:

- Embedding in personal blogs - this is probably best achieved by a simple embed code (which I'm planning to use my gem to build), rather than a full API

- Commercial use - for instance, Spotify (or competitor) might like to display rich lyrics in-app.

The situations which would demand a full-on API, I suspect, would be commercial use. Thus, I'd imagine that any API they build will be private and commercial, providing a (first?) revenue stream.
