The following was taken directly from kungdavid's explanation

Some tidbits: 
On the right side of the page is three small melodies to play
before you start a song. Just press the buttons and play!

1. Shop Theme from Legend of Zelda - Ocarina of Time. 

2. Taiho-kun's Theme from Gyakuten Saiban Yomigaeru Gaykuten
   (That's Phoenix Wright Ace Attorney, I think it's the "Blue
   Badger's Theme song")

3. Ureshii Hina-matsuri ... a traditional song for the
   Hina-matsuri (Doll's Festival) on March 3rd ....


The text on the left side of the page tell us about the internet
music community "Player's Oukoku", http://players.music-eclub.com,
where you can upload your own music tracks and listen to, comment
and evaluate other peoples music. It's just kind of a promotion
text for that site really. Nindori says like "We can't put every
song in the magazine, please use this site to show off your works!"
