Young Alex may spend most of his days rolling balls through pipes and triggering spring-mounted boxing gloves, but that doesn't mean he can't kick back and enjoy a good tune now and again - especially, if it happens to be his own.

Anyone who's caught himself inadvertently humming the Angry Birds theme will know that Rovio's composers are more than capable of knocking up an infectious ditty.

Now, the Finnish developer is offering you the chance to download the equally catchy Amazing Alex theme song from its Facebook page, allowing you to funnel it directly into your ears wherever you are, whatever you're doing.

Oh, and one more thing: it's completely free.
