The iPod, despite its already booming success, just keeps getting better and better. Apple just filed a patent application for a Karaoke function for the iPod (and quite possibly the iPhone by extension), with a diagram pictured above.

The patent is focused on integrating the text files of the lyrics into the song media file, proposing a way to let the text scroll in tune to the music. However, nowhere in the patent application states a way to mute the voice from the song - which is important, because nobody wants to compete with Alisha Keys while belting it out.

Sure, there's already the iSing, and there are also other gadgets in the market that feature a Karaoke function, but the idea of being able to do karaoke on the go with everybody's beloved iPod is nothing short of awesome.
