The first track "Oshiete Sensei-san" is the short version (around 1:15).
All of the character songs (tracks 3, 8, 13, 18) are full length versions,
and all of the seasonal songs are short songs.
The songs are sung by the character seiyuu:
Mizuki Nana (水樹奈々), Nazuka Kaori, Horie Yui (堀江由衣), Nonaka Ai (野中藍).
The lyrics sheets are illustration sheets with the picture of the
character on one side, and the lyrics on the other.
There is one sheet for each character.
The character picture is the same as the cover of the CD.
