might I suggest that you download Winamp for your computer?

if you have a high speed internet, then you can get winamp's radio stations, they have about 5 J-Pop stations, you could be able to see what songs you like :)

Answer 2

Sekai ni Hitotsu Dake no Hana (The Only Flower in the World) by : SMAP - even if you don't know the lyrics, it'll leave you humming the tune for days!

Nada Sou Sou(A Stream of Tears) -a cute song...

Milky Way (BoA)- it's so cool!
