Miro is a free and open-source music player, video player and converter, and torrent downloader. It can sync to Android phones and tablets and other devices. Buy music and apps from Amazon and Google right in the app. Miro is a free alternative to iTunes with more flexibility.

Since Miro can play almost any audio and video format, you'll see all of your stuff in one place. Just 'Watch' your media folders and your music and video will show up in Miro (without moving or duplicating the files)-- and when anything is added to these folders it will also appear (don't worry, Miro won't duplicate or move the files). It's super easy to switch from iTunes.
