The Audacious music player for Linux Mint 14 supports the Monkey Audio APE format out of the box. I recently acquired some music in this format and I found out that the Audacious music player version 3.23 supports this music format. I tried to play this on Windows with Winamp using a plugin; but it would not work at all. This goes to show that the Linux software is better than the Windows alternative by far. This is why using Linux software is better than using software on Windows. Just type sudo apt-get install audacious to install the best music player for Linux. I tried playing this format with the Banshee media player and it had a lot of problems with it; so Audacious is the way to go if you want to play new formats like the Monkey Audio codec.
