smooth progress bar

[jamer007]

Hi, i was wondering if it was possible to have a progress bar progressing in a smooth way.
From what i tried to understand the bar is divided in numbers (representing song seconds), each second passing move the current icon to the next number.
Keeping the same progression logic but multiplying those number by 25, and refreshing the number increase every 1/25 seconds could result in a smooth progression. Or maybe just with CSS transition-X, we could end up with the same result.
what do you think?
