Rap lyrics got you down? Can’t keep up with that new track you just downloaded? Fear no more. A fresh new app for Mac OS X named Capo dropped today. Capo allows you to listen to your music at a slower speed with options for pitch control, marking, and looping. It has a very focused use, but the user interface looks nice and just works. The price is pretty steep at $39, but playing with the trial version is full featured with the only limitation being 5 minutes of audio playback. Maybe you could use it in conjunction with Audio Hijack Pro to save the audio and make your own chopped and screwed mixes.
