Hello, I recently got myself a new iPhone 5s after the excellent results with my MacBook Pro retina. I sometimes download music and in android there were many mp3 files downloaders. From the App Store I downloaded Musify which was meant to be something like that but once I download the song I want it does not appear on my Music app nor I can transfer it to my MacBook (or at least I don't know how to). Does anyone know how to use this app? Any suggestions on apps for downloading mp3 songs? Thanks!
