Downloading amplifyforspotify 1.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The application lies within Audio & Video Tools, more precisely Players. This free Mac application is a product of Ezra Zigmond.
From the developer:
amplifyforspotify is a convenient menu bar app to simplify the way you use Spotify. You can use the program to check the current track, adjust Spotify volume, and control playback without interrupting what you're working on. The tool optionally shows notifications whenever the song playing in Spotify changes, so you know what's playing right away.
You may want to check out more Mac applications, such as iTunesMenu, Total Video Player For Mac or Forty-TwoDVD-VXPlus, which might be related to amplifyforspotify.
