I recommend:
* Maki Goto - Aikotoba (VOICE) 2CD + 2DVD (limited edition)
beautiful package, large booklet, 15 postcards, the four discs has picture labeled (is different for the others).
In CDJAPAN it's 40% off
* Hitomi Shimatani - BEST & COVERS (2CD + DVD)
Very nice tracklist, there are a lot of amazing songs in this BEST.
