It's a good concept-list but Captain, I don't really understand your choices..."Abbey road" or "Spirit of eden"...hummm. "Spirit of eden" is a wonderful record but it's more a perfect winter album to me.
So here is my definitive and perfect soundtrack for an endless summer :
1. The Beach Boys / All summer long (the best of all in this style)
Followers (in alphabetical order) :
The Avalanches / Since I left you
The Beach Boys / Surfer girl
Beck / Odelay
Dodgy / Homegrown (maybe my 2d favourite after "All summer long"
Dodgy / Free peace sweet
The Go! Team / Thunder,Lightning,strike
Hal / Hal
The High Llamas / Hawai
The Millennium / Begin
Mr.Bungle / California
Jim Noir / Tower of love
The Olivia Tremor Control / Dusk at cubist castle
The Pipettes / We are the Pipettes
Phoenix / United
Super Furry Animals / Phantom power
The Yellow Balloon / The Yellow Balloon
Add to this some classic great tracks like "California dreamin'", "Hotel California", "Something in the air" and "Happy together" and you sure won't forget this wonderful summer !
