I liked Ayu's stuff up until GUILTY came out. I am... is my favorite album of hers. I did like a few songs from her last one, but her voice really bugs me these days.
Also, following up on the "repeating songs" thing from the musings thread, I stopped repeating songs a few years ago.
I realized that by repeating them, I get sick of them quickly and don't listen to them for a long time.
Quite a few songs get the waterworks going, too. Sometimes I can be feeling really happy, then a song comes on and I start bawlin'.
