Brand New Day is one of my favourite songs. It's really fresh and it talks about normal life and how we struggle through bad days, but in a nicer way. It's not melancholic or sad, it's just refreshing, like I said.
The second song I love a lot in this album is Missing You. It reminds me of Kelly Clarkson (because she is Kelly Clarkson of South Korea, or so I think). Maybe because her style is a little bit closer to the westerns' and that's why I find it so catchy...neah. I like Asian pop more than ours.
