... that's it, I guess.

This is a difficult one ... I've recently been trying to FORCE myself to listen through every album in my iTunes without skipping a track. It's mostly the long, drawn-out ballads that ruin it for me XD

But a few I can listen through :

L'Arc~en~Ciel's KISS. Yes, even the sugary sweet Yuki no Ashiato.

B'z : LOOSE. My favourite album by them. I even love the ballads, go figure.

ONE OK ROCK : Kanjou Effect. YES. THAT is how you make a rock album.

Any Ringo Shiina album. I love her.

And that's basically it. No Western albums, come to think of it XD

EDIT:

Woops! There is one! Thanks, xLuna1LOVE XD

Caro Emerald : Deleted scenes from the cutting room floor
