which songs would you recommend to someone as "songs you do want to miss"?  

I'd recommend Unhearted by Automatic Loveletter, just because it's been stuck in my head all day.
I think it's awesome that you're working on singing English songs. I know that if I was trying to learn how to sing songs in Chinese, I'd give up. It's cool that you have that initiative to try something new.

i would suggest..cry me a river by justine timberlake its sweet and slow and word by word..the next one is..lavista bonita by madonna..a sweet classic too that i recommend to you and some bit of we ride by mary j blige..those should fit in your shoes..
