Thank you for reminding me, Scrump...I downloaded it in the .ogg format (a slightly better format than MP3) and decided to try it in GOM Player a totally free program which will play almost any format! (Video or audio)

In GOM Player there is a 'control panel' with a feature to control speed...at about 80%, it sounds pretty good! It also has a built-in equalizer and volume control.

In GOM, you can even control brightness, contrast and color saturation in videos as they play!)
