The perfect song

Following an online discussion about whether it was possible to create the perfect song / track, whether that would be a good thing or not (some times it is the flaws that make a track unique), we got thinking as to what some examples might be.... Tracks that grab you from the start, bewitch you, stay with you and have no element of - "yes it's good, but I just wish they hadn't....". There is nothing that you can think of that should be, in any way, changed. It is interesting that this sometimes makes for a song which is successfully covered by many artists (ie. I Feel The Earth Move), but other times it stands clearly as the definitive or only version (anyone prefer the Tom Jones version of Kiss?).

We came up with a diverse collection. A playlist of perfection:

Tangled up in blue - Bob Dylan (actually, all of Blood on the Tracks)
Don't ya hear me callin' to ya - Fifth Dimension
Wild World - Cat Stevens
Song with no words - David Crosby
Kiss - Prince
The day before you came - ABBA
Shot by both sides - Magazine
Blister in - Violent Femmes
Novocaine for the soul - Eels
My Funny Valentine - Chet Baker
Song 2 - Blur
Le Freak - Chic
I Feel the Earth Move - Carole King
Being Boiled - Human League
Common People - Pulp
Hurt - Johnny Cash
Un homme et une femme - Michel Legrand
Get Carter theme - Roy Budd
Pithecanthropus Erectus - Charles Mingus

Any other suggestions?
