I may be choosing more Rock based stuff, but I hope I'm on the right track.
That said, Syd Barrett was solid with the Pop Hooks that GRABBED you. Technicolor Sound, Black and White Footage...pretty rare stuff (until it got You Tubed)

You want Pop? Here's Psych-Pop from the Pop Side of the spectrum. The Gibbs had a sharp instinct of knowing what trends to catch for their style. My favorite era was certainly the Bee Gees 1'st-Odessa era.

One last one (for now...). Pure class!

Now that my computer has finally recovered from being brokeded, I'll post some more youtube videos to break yours.

Some strawberries


Some colour


Some patriotism


Some kraut

Some Mods...of the '66 kind

Some Painter Men.

...and some Traffic!

So are some psychedelic songs that aren't pop?

The Beach Boys: Good Vibrations (1966).
