And music tends to be highly dynamic, with lots of quieter passages in between peaks, the average is much lower with cooling time between the big spikes.
Is there something that makes you think the posts in that link wouldn't carry 60 amps without a problem? It really doesn't have anything to do with the dynamic range of music and how much amperage is going to the driver. It's really just a question of there being enough conductor there to handle the current.
Do you think there would be a problem running 2500 watts RMS through those posts into a 1 Ohm load? That should be about 50 amps.
