Ayer comentaba sobre la clase PHP para enviar canciones a last.fm. Bueno dado que lo voy a utilizar desde CakePHP lo más lógico era construir un componente, y gracias al HttpSocket de CakePHP el código se redujo bastante. Aquí les dejo el código para usarlo libremente (MIT License)
< ?php
/**
* last.fm component for songs submissions
