[Rock Steady]

Hmmm.....

Jpop:
BoA / Very easy to get into and she has some unforgettable songs, though I recommend her Korean stuff over her Japanese stuff. Listen to her albums Atlantis Princess and Girls on Top
Nami Tamai / Very upbeat techno songs and she has a very powerful voice. I recommend her album Make Progress for new fans.
KOTOKO / She's sometimes techno and she's sometimes soft rock, but her songs are very easy to listen to and she has a gorgeous voice.
YUI / She has very feel-good songs that are addicting
OLIVIA / She's too good for words, just listen to her.
Rie Fu / Very pretty mellow songs that are really easy to get into.

Kpop:
TVXQ/DBSK/Tohoshinki / If you're gonna listen to them, listen to their Korean stuff because it's so much better than their Japanese stuff. They all have gorgeous voices and I recommend their album Rising Sun.
Big Bang / great dancing, vocals, raps, songs, everything. You should defiantly give them a listen.
SHINee / Very catchy, pretty songs with very good vocals.
Wonder Girls / upbeat and fun. That's pretty much the only way to describe them.
Lee Hyori / great hip-hop and R&B songs mixed with good vocals.
Super Junior / lol just listen to them, you'll like them.
Rain / This man is godly, you must listen to his Rainism album.
Girls' Generation / Ever heard the song Gee?

C-pop:
S.H.E / gorgeous vocals and fun songs
Jolin Tsai / She has very pretty ballads mixed with a very cute voice and face
Show Luo / awesome, upbeat songs and terrific vocals. I recommend his newest album Trendy Man.
