Just in passing to say that I recently posted a Javascript library that implements the fpcalc and also the AcoustID service. I named
Gimme-the-song. As I said recently on an issue, for me the best part is that it makes the developer life so much easier; by installing fpcalc underhood and also making the request to the AcoustID service (respecting the 3 requests per second, of course). For any bugs or improvements, let me know. And also I'm developing a web app that will use this library to recognize songs.
Huge thanks guys, you made my developer life so easier by giving to the community this awesome library. See ya!
