BoA - basically almost all ballads from new album:
Implode
M.E.P
Ordinary Day
Don't Know What To Say
Romance
Super Junior - Don't Don
Shimizu Shota - Sakura (his style it's not my cup of tea and I dislike his voice, but that song is beautiful!)
Rina Aiuchi - Nemurenu Yo Ni (lyrics made me love the song which I hated earlier
)
Key (SHINee) - Tik Tok (THE BEST COVER EVER
)
SNSD - that new song from cartoon OST... Haechi?
