I did not enjoy this album fully like other Coldplay. This was a summer of senior year album for me, I was very into my new MacBook G4 12 inch, photography, yearbook. Speed of Sound was def one of the songs I listened to the most. Strong sense memory of the aftermarket head unit in my VW golf. And burning a CD with this on it and playing it loud. Sound feels sad to me and reminds me of the coming change of high school ending and my friends from the previous year moving on.
