Its easy to track down iPhone apps that name catchy tunes, but it now looks like Apple wants to spare you from having to search in the first place. Bloomberg sources claim that a future version of iOS will incorporate Shazams song recognition in the same way that the existing mobile platform integrates Facebook and Twitter. While built-in music detection wouldnt be a new idea (just ask Windows Phone users), you could ask Siri to tell you whats playing rather than hit a button.
