MP3’s come in different sizes and bitrates, but can you hear the difference between an MP3 encoded in 320 kbps and one that is only 64 kbps?  (kbps = kilobytes per second)

Go to www.mp3ornot.com and listen to both clips.  One of them is 320 kbps and the other is at a lower bitrate (128 kbps).  Put your ears to the test and use that as practice.

Then go to www.playbackradio.com/Mp3bitrate.html and come back here to leave a comment on what you think.
