well, the production crew just want to create a song that contrast with the warfare, the violence of the show. the song has a saddening effect and grows on people after listening to it after a few times. at first i was shocked like everyone else. found it weird and all. the song is more suited for an ending song, whatever the case, this approach is fresh and served as a rap up for the whole series of gundam seeD+ destiny.

(upbeat songs have always been around for all the time to hype up the series, a slow song might just do the job to end everything)
