My favourite Eurobeat mix is AUDIENCE (Euro-Power Mix).
It's also my favourite rendition of AUDIENCE.
Prettiest Hamasaki Ayumi song?
It really depends on how you define 'pretty'.
I would class JEWEL and forgiveness as 'beautiful' rather than pretty, so that takes them out of the equation for me.
For me, the prettiest would have to be a tie between Will, End Roll, SCAR, teddy bear, no more words and Sweet Season.
EDIT: I just remembered HAPPY ENDING. That one takes the cake for being the prettiest of them all. <3
