This app slows down the track as well as changing the key. But that is only the start. You can loop sections (with the help of an audio wave image), organize your playlists, and even import audio from video. The free download comes with the slowdown, pitch adjustments, loop features and lyrics display. This is a great tool and highly recommended, even just for the basic download version.
