Wowhead has rolled out some pretty exciting site features today. First up is their new music and sound player which allows you to play sound files from the game such as boss emotes, or listen to zone music as shown in the screenshot above. By visiting a zone's page, for example Storm Peaks, you can browse through all of the various music that plays in that zone.
Aspiring Loremasters take note! Also added is the ability to see what quests your character has completed anywhere in the game. You first need to use the Wowhead profiler to import your character, and then you will be able to view any quest on the site and see if that character has completed it or not. If you pull up a list of the quests in a single zone you will be able to see, at a glance, what you're missing. You can even track multiple characters at the same time. Head on over to Wowhead to see the full rundown of the new features.
