Just as there are modules to help you read ID3 tags, there are modules to help you read the data. For example, MAD http://www.underbit.com/products/mad/ can be used from Python http://spacepants.org/src/pymad/ so that you could get the length of a track in milliseconds with something like import mad print mad.MadFile("a_track.mp3").total_time() There are other modules for other libraries as well.
