To be pedantic, writing is what harms flash memories (which are within SSDs, among other things), not reading. Dunno how much writing the radio does, but I'm guessing not a whole lot. Your USB flash stick is just as vulnerable to degradation, if not more so, as the SSD is. SSDs at least has some logic to remap sectors when things go awry.
But, either one being used to serve up a couple dozen songs a day will last for years and years.
