Not that we aren’t fond of people singing along with tunes on their iPods, but quite frankly, most of you are horrible. It isn’t your fault, we know you can’t hear yourselves. So, we aren’t sure if Apple’s latest patent, uncovered by MacRumors, is the greatest.

The filing is for karaoke-esque software on your iPhone, where you sing along to scrolling lyrics on the screen, and are rated for how well you do. Think of it as a personal Rock Band game, without the guitar and drums. Yes, we know that’s just karaoke.

More interesting than a built-in app, though, would be if Apple opened up APIs to access such software. We could see interesting software that could take advantage of tone and pitch recognition. So, with mixed feelings, we can only wait and watch out for karaoke in future iPhones.
