Clementine

Clementine is an open source audio player designed for Mac. This feature-rich program can successfully replace the highly popular iTunes app, being able to play your favorite songs and help you listening to various online radio shows from one place.

The utility works with a wide variety of audio formats allows you to create and save playlists, and lets you use shortcut keys to control the player. In addition, you can easily configure the settings from the Equalizer screen and play your music while watching various animations in the Visualization window.

Another thing I like about this program is that it comes with an integrated audio converter. This built-in tool comes in handy if you're dealing with incompatibility issues between one of your audio files and the media device (mobile phone, tablet, etc.) or app you're using for playback. The utility supports various output formats, such as FLAC, OGG, OPUS, SPX, WAV, and many others.

You can listen to various radio channels or play the music from your Dropbox or Spotify account. Just configure several settings in the Preferences menu and you're good to go.

To be honest, I have nothing bad to say about this program. It offers you plenty of useful features, works with dozens of audio formats, and is free. So, it's definitely worth a try.
