I've tried two ways to disable the Start-up songs.

First option is manually stopping the sound by pressing the mute key(F10) every time I wish to shutdown or restart my mac. however, it's the temporary solution.

Another way is using Arcana StartupSound.prefPane.

if you'd installed that one, at your System Preferences >> Other , you'll see 'Start Up Sound'

I've tried this one and it really works on my Mac.

OK - I had this problem and it was really annoying.

Why, I asked myself, was the startup sound playing so loudly through the speakers even when I always have my headphones plugged in, and why did it still play so loudly when I had set the volume to the minimum or muted it entirely before shutting down.

Here are the answers to these questions:

1. The startup sound is always played through the internal speakers, even when the headphones are plugged in.
2. Changing or muting the volume while headphones are plugged in only changes the headphone volume settings, not the speaker volume setting.
3. SOLUTION - take the headphones out, reduce the volume, that will be the volume of the startup chime, then you can plug the headphones back in and alter that volume as much as you like.

(note that you could substitute the word 'headphones' in this post with 'external speakers', if they are plugged into the headphone jack, I imagine they will have different volume setting to the internal speakers as weill)

This software enables you to control the volume of the startup sound of your Macintosh computer from Mac OS X.
