mp3 libs and programs

[Jay]

I'm writing a python script that involves playing mp3 files.  The first
approach I had was sending commands to unix command-line programs in
order to play them.  I tired mpg123 and moosic, but there was a key
feature to my program's success that's missing.  SEEK!  I need to be
able to start playing a song at an arbitrary point in the song.  I
can't find anything to let me do this.  Does anyone have any advice or
has anyone needed something similar?
