PixiApps has a teaser for Ecoute 2.
I wouldn’t be surprised to see it on the first day of the Mac App store. Their projects page lists it at 98% done.
EDIT: There’s a brief preview of Ecoute 2’s Social Preferences UI on Daily Motion. You can share with Facebook, Twitter, and scrobble to Last.fm. Not sure I would have picked the Silent Hill music to go with it, but I sure like this guy’s taste in music.
