The way I look at the word "per" is to just turn it into a divisor sign, 
so that a 60 bpm song would be:

60   beats
    --------
     minute

a 120 bpm song is twice as fast, and hence has twice as many beats in a 
minute, etc.

explanatory PS: 60/bpm would equal 60/beats/minute == 60 minutes/beat 
which would actually be 1/60 beat/minute , read as one sixtieth of a 
beat per minute.  At least that's the way I would read it...
