Any good songs from KANA NISHINO?

Question:

i have only heard "best friend" and "brave heart". and really liked them!

Answer:

Some of these more recent Kana Nishino songs have been top-ranked on the RIAJ Digital sales charts:

Motto...
Dear...
Best Friend
Aitakute Aitakute
If
Kimi tte
Distance

One song I particularly like from her is "Style" which is a theme song to the Japanese anime Soul Eater.
