I think the fascination with COVERS is the novelty factor. Japan loves American Pop, so hearing J-Pop classics in English is probably exciting to them.
I've been a bad BENI fan by abandoning her after Zutto Futari de and hearing Diggin' On You, but I feel like I cannot get away from her <3.
BENI's vocals are so smooth, sweet, and powerful. I've never seen an artist, whether it is in the States or in Japan, improve in such a short span of time.
If you listen to songs like Here Alone and Harmony to songs like 瞳をとじて and TRUE LOVE, you'll see how her voice has evolved from hollow and empty to strong and beautiful.
After hearing COVERS, I've come to realize that BENI can show American Pop artists how it's done. BENI has something to her voice and her sound that is unmatched in the States.
You know you're doing a good job when you're being charitable by letting Crystal Kay ride your coattails, outsinging JAMOSA, releasing music consistently unlike her twin sister May J, and inspiring Thelma or her record label to copy you... actually it might be Che'nelle, but judging by the timing, I'd say BENI inspired Thelma to release a COVERS.
Anyways, BENI has made a signficant improvement in the J-Pop realm, and it seems like she's here to stay.
I think these COVERS albums has helped BENI receive the recognition she deserves, so she'll probably release new music after COVERS 2, and she'll continue to slay.
Now that I think about it, it would be nice to see BENI release music in the States, since her music and voice is 10x better than most of the artists in the States.
P.S. When is 嘘つき being released? I know it's on the soundtrack CD for the PSP game, but it would be nice if she released the song on one of her albums.
