Enter Ecoute.
Ecoute, from PixiApps, is a minimalistic, powerful media player for Mac OS X. Taking on the UI theme of a bevy of new Mac apps such as Twitter for Mac and Pixelmator, Ecoute features a collection of rounded dark elements, relying on the small and understated to achieve its aesthetic charm.
Ecoute allows the user to have a desktop controller, similar to that of CoverSutra. Shown here is the Baptême theme; although not currently in full use, PixiApps aims to have a full theme center where one will be able to download themes and switch them in Ecoute. There are currently a handful of themes available for download on their homepage.
Ecoute allows synchronization to last.fm, Twitter, and Facebook. While I'm not one for trumpeting my music to my Facebook or Twitter, the last.fm "Now Playing" and scrobbling integration is very nice (and was effectively the last nail in the coffin for CoverSutra). Ecoute also has support for the Apple (physical) remote and Growl notifications.
Plus, the icon is eons better
than that of iTunes 10.
(Yeah, that's live artwork.)
Ecoute is available for $10 from the creator or from the Mac App Store. There is a free demo available on the creator's page.
