Take a look at the subject line. We're primarily discussing CDs (amd 
DVDs which are in all relevant respects the same as CDs).

The question of what to do with USB media is different in several respects:
USB media are relativly few in number. I regularly buy magazines with 
CDs or DVDs attached: I have dozens, maybe hundreds, of those. I note 
that blank CD and DVD media are sold in spindles of up to 100. In 
contrast, I have about four USB disk enclosures with notebook or desktop 
drives inside, and one USB2 flash drive. The filesystem labels on those 
are mostly my choice, and I have no problem recalling that my flash 
drive gets mounted at /media/USB_DISK.

The CDs and DVDs filesystem labels are chosen by the person who prepares 
the ISO file, and there are three ways I obtain them:
1. Incidentally to the purchase of a magazine or book to which they are 
attached. We might as well include commercial software here as the 
significant difference is which, the media or other materials, is of 
primary value.
2. Burned from ISOs downloaded, whether they contain Linux, *BSD, or the 
latest firmware for my Acer laptop (yes, the firmware comes on an image 
which is to be burned to CD)
3. Self-created images, such as for backup or data transfer.

In the first two case I have no control over the filesystem name, and 
unless and until I mount the media I have no way of finding out.

In the third case I don't usually bother using a volume label as the 
essential info is what I write on the disk (write-once) or the label I 
insert in the case (RW media).

I reiterate: as I see it the requirements for CDs and DVDs on the one 
hand and USB media on the other hand are different. The latter, I the 
owner control, whereas in the case of the former, I the owner do not 
control and generally don't know.

Showing the volume label on the desktop is a different question, and my 
answer to that is that it's a fine thing to do. It happens after it's 
mounted.
