Perfect Pop Songs

Those with the kind of music, lyrics, performance, arrangement and production that you could easily repeat all day.

How about starting with this one? Somewhat outside of her usual cannon and none the worse for it. Perhaps also a contender for the sexiest vocals ever?

Louie Louie  by Julie London
"Wichita Lineman" by Glen Campbell.

I like the "Winchester Cathedral" nomination as well.

Just for contrast I’ll toss in "Highway Star" by Deep Purple. Once the opening riff starts you are helpless.

and for something more modern:

Alesso - Heroes (we could be) ft. Tove Lo   .....  loud but awesome..

Whip it, by DEVO..

Mony Mony, by Billy Idol..

Different "Pop" anyways.. For me Pop ya got to be able to dance to it..

Acapella ballots don't count. :-)

More current,

These two (indie classics?) kind of remind me of each other what with both being drenched in reverb and echo.

The Jesus and Mary Chain -
Some Candy Talkin (1986)

and Cigarettes After Sex - Starry Eyes (2012)
“Windsurfer” by Roy Orbison. 
“That Happy Feeling” by Bert Kaempfert.
