I too say spring for the 500GB Blue. Vibrations can be a bitch with the 7200 Blacks. Fine for a mini or a Time Machine drive but not so nice for a laptop.
Can I make a recommendation? I'm not sure what your budget is but 15 bucks shouldn't kill you. Go with the 500GB 5400 drive. Vibration/noise will be less and battery life will go up by 15 mins.

I have a question. I ordered a 320GB Black, and I'm supposed to get it tomorrow. I have not gotten my MBP yet, but I will probably get it in the next week. From what I've read on this thread, the Blue is just as fast as the Black. Is this seriously going to be the case even when doing intensive tasks like music production? If that is the case, I'm tempted to return the drive and get the Blue.
Two things, though. First, I'm going to college next year, so the 5 year warranty on the Blacks is nice vs the 3 years on the Blue. Also, the drive I purchased for $80 is a RETAIL drive, in the box, which I like. I keep hearing horror stories of Newegg OEM drives failing. So for $15 extra, I get a bigger (slower?) drive that is OEM. I don't know what to do...
