ALL BUONO! songs if you can, please!!
Add some Aichan songs like: Cosmos, Yume Kara Samete or Yuki Ai Anata Suki...i would request the concert solos but maybe is too much aibutt to handle (is all good too)
I think all high-king songs are good; i like cinderella complex or destiny love
And obviously can't be called h!p if you don't include Mano Erina (Sekai wa Summer Party, Kono Mune no Tokimeki wo, lucky aura or anyone) and Kirarin/Koharu stuff (milky way please)
From C-ute i recommend... Tokaikko Junjou, Soku Dakishimete, Forever Love, Edo no Temari Uta II, Bye Bye Bye!, Go Go Go!... and JUMP (very please)
from morning musume, from the last 2 albums i like SONGS, Mikan, Kanashimi Twilight, Genki+, Egao YES nude, Sexy Boy, Ambitious... lol wth, play rainbow pinku too
