oh. I guess that's probably because Chinese tend to be more
sentimental. No lah, some songs, SOME, are truly written from
experience. For example, David Tao wrote "Melody" and it was about
his ex-girlfriend of 6 or so years, Melody. He also wrote Black
Tangerine to express his thoughts after the 911 incident.
I don't see anything wrong in producing music for money. In the
first place, I don't believe one will produce music entirely for
money. There must be some interest in the music itself. So long as
the music entertains, I guess it's ok? Some of Wang Li Hong's songs
are pretty entertaining. Those songs don't sing about love and like
and this and that but rather about, for example, the weird things
that can happen to somebody. And remember Andy Lau sang about our
favorite seat in the toilet - the toiletbowl.
I can't say much about Jay Chou, cos I'm not quite familiar with
his music. But he seems to take pride in his mumbling. Cos in the
g-music awards he mentioned that "I will keep mumbling in my songs!
thank yoU!" 
lol.
I used to have dislike for Mandarin Pop too, because all the songs
appeared to be singing about the affairs of the heart, and they all
sounded similar, same old boring style. But in recent years, new
artistes have sprung up and production of new kinds of music like
those that are a fusion of say, jazz and hip hop are seen.
Some time back I had a thought... erm, maybe Mandarin pop isn't
lousy/boring, just another genre to add to the list?
My humble opinions are as such for now lar... but I'm so tired
after a long day at school I probably don't really make sense of
what I'm saying.
