You can technically run Linux on a USB stick. You need to install the boot partition in the system itself not in the USB partition.
But I seriously recommend against this. I once ran ZorinOS like this back in the day, when I was testing the waters and that thing was stuttering. I ran it off a USB 3.2 stick and even then it was slow. Not to mention the heat and the damage to your USB port.
Stay away if possible.
Well its also a simple browser so it will preview the HTML page like any other browser would. But I don’t know about audio files though.
