Don't quote me, as I've only seen this ad once, (and to be honest I was concentrating more on the woman in the underwear), but I believe the song is "Fade Into You" off of Mazzy Star's "So Tonight That I Might See" CD. Check the sample of it on CDNow: http://www.cdnow.com/cgi-bin/mserver/SID=1117731545/pagename=/RP/CDN/FIND/album.html/artistid=MAZZY+STAR/itemid=328686 If you like this song, you should check out their other CDs. Their songs can be "much of a muchness" (as the Brits say), but when they get it right (like on "Fade Into You"), their songs are transcendent (listen to "Halah" on the debut "She Hangs Brightly", or "Disappear" on "Among My Swan". Also check out "Sometimes Always", on the Jesus and Mary Chain's "Stoned and Dethroned" CD. It's a duet between Hope Sandoval (Mazzy's chanteuse) and James Reid of the amazing JAMC.
