The song of the day is Kira-Kira Sensation! I chose this song because it's catchy and the lyrics are beautiful. When I hear this song, I almost want to cry because it's one of the last song in the anime. Also, I just noticed that on the cover of the album, Nozomi, Eli and Nico are crying... Kira-Kira Sensation is a mix between a sad and a happy song. But I like it a lot. It's definitely one of my favorite µ's song. 

Donna ashita ga matteru ndarou? Nante ne
(Boku wa) Bokutachi wa sukoshi zutsu tesaguri shiteta

Hagemashi atte butsukari atta toki de sae
(Wakatteta) onnaji yume o miteru to

Mezasu no wa ano taiyou
Ookina kagayaki o tsukamaeru
Itsuka no negai e to chikadzuite
Hikari no naka de utau nda Sensation!

Kiseki sore wa ima sa koko nanda
Minna no omoi ga michibiita basho nanda
Dakara hontou ni ima o tanoshinde
Minna de kanaeru monogatari yume no Story
"Mabushii na!" "Ii na!" "Oide yo!"
"Ureshii na!" "Ii na!" "Motto ne!"
Hitotsu ni nare kokoro… KiRa-KiRa!!
