Soundtracks to movies became popular back in the 70s.  One of the best was the track to Grease.  Way good tunes, and I know I still can picture Olivia Newton-John in that leather attire.  But the best soundtrack of all time- with a nod to Star Wars- is the songs to Rocky.  Here we are, nearing the 4th decade of the original Rocky, and when that music starts, I feel like running up some steps.  And you are liar if you don´t think about hitting some hanging beef when that song hits.  

     Of course, that Darth Vader theme music is wicked.
