The default Audio Player shipped with Linux Mint is Banshee. Menu > Sound & Video > Banshee. For whatever reason, Banshee does not ship with any audio files, so we have to FTP some audio files into Linux Mint. This might be a good time to set up Pure-FTPd, so we can file transfer some audio files into our Linux Mint machine. After an audio file has been transfered, move the audio file into the music directory in Linux Mint. Then, in Banshee select Media > Import Media > Music, and the audio file should be imported into Banshee. Play the song.
