Depending on the bitrate, MP3 will still carry 20 to 20,000 Hz.  FM  
doesn't transmit anything above 15,000 Hz.  If you happen to be in  
your 40s or older, though, you may not be able to hear those  
frequencies anyhow, so the point may be moot.  Hint: The flyback  
transformer whine from a CRT television is at just under 15 kHz.  If  
you can't hear that anymore, don't let anyone at your local stereo  
shop try to sell you tweeters. ;)

FM also involves the loss of some stereo separation and the addition  
of a significant amount of hiss.  A lot of FM stations also use heavy  
compression, but I don't know if the little home transmitters contain  
any sort of compressor or limiter.

That's true enough.
