It's a song by SOUTHERN ALL STARS.
I think it was the part when she sang a song she did in karaoke when it was actually what Max always did LOL
And it was in the same episode as SEASONS.. but apparently, I guess the KinKi Kids' voices + Ayu's = NOT GOOD :p
http://ja.wikipedia.org/wiki/チャコの海岸物語 It's in Japanese.
"Chako no Kaigan Monogatari" aka "Chako's Coastal Story".
