Obsessive songs

From time to time I just run into songs that I just can't get enough of listening. Currently there are two of them: one from the movie Closer, "The Blower's Daughter" by Damien Rice; see also the first scene of the movie which is amazing. I first heard the second song in a commercial of Connex (a wireless phone company from Romania). Then a DJ from a radio station also liked it and started to broadcast it, so I was able find this song (it's from the 80's): "Supergirl" by Reamonn.
