I like your list illuminatile
Zero cool, your list is alright
bigmack, your list is probably too hiphop for me, but then again, we are on a hiphop board.
Anyway
I'd probably add songs like
Dante Thomas - Miss California (bet you ahven't heard this in ages)
Liberty City - I met her in miami (yeah that's another one you probably haven't heard in ages)
Robert Miles - Children (one of my favourites)
Golden Girls - Kinetic
Eric Pryndz - Call on me
Bob Marley - The Sun is Shining
Sorry if this list turned out a little dancy but that's what i feel summer tracks are.
I've got so many more, but i have no time.
Oooh, and brian adams - Summer of 69
