I don't have time to do as good of a job grabbing all the songs as Tsukiru did, but here's how to get the latest ones.
Step 1: Find the number of the song you want to get in the list below
Step 2: Point your browser to
http://sony.net/united/clock/assets/sound/theme_song_of_world_heritage_##.mp3, where ## = the number from the list
Step 3: Ctrl+s to save the mp3
For instance, if I want the theme song for Ogasawara, I find that it's #40 in the list, so I go to:
http://sony.net/united/clock/assets/sound/theme_song_of_world_heritage_40.mp3
Song list (if it changes in the future try going to
