LEDs don't burn out with nearly the same frequency that an incandescent bulb does. It's the nature of how it works.
And, anyone with any basic soldering skills can replace an LED. Sure, it's not as simple as unscrewing a lightbulb, but it's not that difficult.
I do agree with you on the music though...it is pretty bad. I've watched the Hong Kong version online and wasn't really all that impressed. Give me the classic MSEP any day.
I am a big fan of the HKDL Paint the Night music. I have watched (and listened) to numerous videos and it is perfect. My wife and I have joked about a trip to HKDL solely because of Paint the Night!
That's why the world is great...all different opinions out there.
