Well, it would be hard to talk of a place as I pretty much only listen at home, but time - I think, yes. Octavarium is definitely spring, that was when I was getting into DT, and the first album I had... Then SFAM is summer, and strongly related to some memories of my own, and so is Train of Thought. Falling Into Infinity is, well, Christmas-related for me, as I got it as a gift, and was listening to it a lot afterwards. Also Systematic Chaos and Black Clouds & Silver Linings also count as summer, as both were released in June and I was obviously addicted to them after they were released (it's hard to believe it's already three and half a year since the release of SC... wow). Not much connection for any of the others, though.
