When Mighty arrived in 2017, the device offered the convenience of offline playback for Spotify. In other words, you could take your favorite tunes anywhere -- and you didn't need your phone to do it. Basically, it's an iPod Shuffle for any albums, songs, playlists or podcasts you've made available offline. The company (which goes by the same name) returned in 2018 with the updated Mighty Vibe, a device with much improved Bluetooth range and more consistent battery life. Of course, there was still a key issue: it only worked with Spotify. Well, that changes today. Mighty now works with Amazon Music.
