請幫忙找找,有冇人知呢段片開頭首歌名呢?

Hi,
The first song is Where'd You Go by ForMinor and the other song is Speeding Cars by Imogen Heap. I hope I can help you. ^^

Btw the name of the songs are there, maybe you didn't notice it.

i am not too sure about that, but that tune sounds a bit like Danger Zone (Top Gun OST) http://www.youtube.com/watch?v=YIO2A7pKnpM
