Do you ever wonder why certain songs (or even just parts of songs) have the power to excite you, to move you emotionally, etc? What about certain chord changes or sequences?

As an example, I just listened to Marnie Stern's 'Transparency Is The New Mystery' for the first time (cheers, Yesiamaduck) and felt that swell of feeling at the chorus. Then it was almost dampened by the realisation that... I ALWAYS enjoy that particular chord sequence. I don't quite possess the musical knowledge to describe it, but you could form it with powerchords as thus (key is irrelevant):

D--4---6---7--
A--4---7---7--
E--2---4---5--

In the example of the Marnie Stern I think it's something closer to this:

G--6---8---9--
D--7---9---9--
A--4---6---0--
E-------------

Anyway, tabs aren't the point. Do you know what I'm getting at? Even in a song I might otherwise think of as crap, there could be a particular chord (or chord change) that gets that kind of reaction. Other examples off the top of my head that share the aforementioned chord sequence:

Nantes by Beirut
What I'm Trying To Say by Stars (middle eight/end)

Aaaand my mind's gone blank. Anyway, without delving too deeply into tedious muso wankery, have you noticed certain elements or progressions in music that you find yourself constantly enamoured with? Do you think it ruins the effect to over-analyse it?
