Question:

Here's the Link

http://grooveshark.com/s/Yuuki+100+/3oEi…

I know the first part is 100% Yuuki by Hey! Say! Jump but around 1:20 it changes into another song that's totally different from the first song....does anyone know the name of the song or the person who sang it? If you have a link or something could you share it with me?

Thank you :)
