"Déjà vu" brings you good memories of Hong Kong and RTHK amidst beautiful songs that you will sing along. Just like what "Yesterday Once More" says:
"I'd listen to the radio
Waitin' for my favorite songs
When they played I'd sing along
It made me smile.
Those were such happy times
And not so long ago
How I wondered where they'd gone
But they're back again
Just like a long lost friend
All the songs I loved so well."
