OK, one more time for them as can't read - the list was decided by chart action, not someone sitting down and going "ooooooooo, like that one, I'll put it at #7 !!!"
"These 30 hot tunes with summer-specific themes are ranked based on each track's performance on the Billboard Hot 100 chart from August 4, 1958 -- the inception of the chart -- through the chart dated July 3, 2010. Songs are ranked based on an inverse point system, with weeks at No. 1 earning the greatest value and weeks at No. 100 earning the least. Prior to the Hot 100's implementation in 1991 of enhanced radio and sales information from Nielsen BDS and Nielsen SoundScan, songs had shorter reigns at No. 1 and shorter chart lives. To ensure equitable representation, earlier time frames were each weighted to account for the difference between turnover rates from those decades and the turnover rates that have occurred since the advent of Nielsen Music data."
For example, this is how "Surf City" got to be #4:
Debuted June 15th 1963
68-20-10-7-2-1-1-3-7-11-15-25-44
I'm assuming they awarded 100 points for #1, 99 for #2 etc., etc, so the song scored 1099 points.
Hmmm thought Kokomo would be on it then
Wasn't a summer hit - charted September 3rd 1988, hit #1 on November 5th.
