i just found out about her yesterday and i'm very impressed!
My favourite type of music is electronica/dance so it's rare that i enjoy ballads, especially 4 (i don't know how to classify traume exactly) in a row, but i like all of her songs. her voice is powerful and unique and seeps with emotion in every song.
overall, i think 'jidai' is better than 'dear my friends.'
here are her songs in my order of best to....least best:
Trauma - i love how her voice flows in and out of the synth especially at the start with the dan dan dan dan dan's. musically i like it alot too. the talking is very cool at the end.
Jidai - the uniqueness of her voice is really evident in jidai. plus, there is a folk-y sound to the song with i really like. i like it more and more each time i hear it!
Dear Ladies -

I LOVE the way her voice cracks in the chorus, it really makes the song.
Dear My Friends - i know this is generally everyone's favourite, but to me it's her most ordinary song. it's ok nonetheless.
soooo looking forward to more singles and an album!!!
