Using Windows 8 in Metro should be quite an easy mission, given the fact that the operating system already comes with multiple built-in apps, but those who want more features clearly need to have a look in the Store.
In case you wish to download and install a new tool to play your music, you may want to have a look at The Best Audio Player, a simple yet very powerful program that offers support for the commonly used formats on the market.
For example, the app supports WMV, MP4, MP3 and WMA, while also comprising dedicated options to play music in the background.
Last but not least, The Best Audio Player comes with settings to increase and decrease the speed of the audio playback straight from its main window.
