I was wondering the same thing. I haven't found any information on who that is either. Please let me know if you find out. dwv0830@aol.com
I searched the title at CD Connection and found 150+ matches but no one that sounded right. I thought I had it with Cranberries but it wasn't the right song, darn!
Maybe it was produced specifically for the commercial and is a no-name artist. We probably need to hunt down the approrpriate Sony ad agency.
