I have never heard of SingerSen but she sounds amazing. A welcome addition to my life

anyway,
Spread the Eiko love
I agree with megumi that Eiko is good. Eiko brought a new musical perspective to my life lol. Hikki and ayu had to make room for Eiko with regards to my absolute favorite artists. I actually recently lost a lot of my music and need to find these albums.
I'm a huge fan of her Hikari nadeshiko album and her O album.
some others that I prefer from her more than the ones already given.
I can't suggest all of the I've Sound girls but I also like some of MELL's stuff:
