Web-API for shazam or a similar service?

Question

Shazam on my Android phone works great. Now I'm looking for an api for Shazam or a similar service.

This service should take a small part of a song and should return the metadata of the song. (title, artist)

Answer 1

Not an answer to your question, but there is a really interesting article about how Shazam works[1], including a research paper from one of the developers of Shazam.

With propers backend resources, it would be possible to send a music snippet to the server (per a RESTful API perhaps?) and return a guess. Someone should build this.
