I'm not going to subject myself to "C'est La Vie" even once. It's too much. Maybe "Kiss!2 Bang!2" (I've seen the title alternate between that and "Kiss! Kiss! Bang! Bang!")... Any other suggestions? *shrug*
Welcome to being 23, Ayaka. Hope you have a pretty good Birthday, today.
Sayonara ~ Sweet Days is a must listen. One of my favorites. <3
I'd also recommend Cross My Heart. It's not from PGSM but it's definitely one of her better songs. And by better I pretty much mean best, her English is like...freakishly perfect. It took me a while to convince myself it was really her singing. o_o;
