Cat Power’s Chan Marshall is one of our most gifted interpreters of others’ songs (if you haven’t heard her The Covers Record or Jukebox, they are quintessential cover albums that you should get onto your Christmas list).  Here’s a little secret: we don’t watch a single commercial on television.  Despite this, we can’t stop watching and listening to Cat Power’s take on Have Yourselves a Merry Christmas in the iPhone commercial below.  Ms. Marshall’s had some tough Christmases over the years, which you sense in her version of the song.  She’s never been able to hide her heart on her sleeve.  Here’s to the happiest of holidays to one of the greats, Chan Marshall.  And also with you.
