I can't imagine this hasn't been noted before, but it just dawned on me that I've been seeing the Kraft cheese commercials, featuring Enya's "Only Time" for quite a while!
I've heard it, but I didn't know the song title. It's one of the only two or three Enya songs I like.
(One of which is, of course,
Orinoco Flow, which has also been used for at least one commercial.)
