Queen - Under Pressure
With a bass line that would later help Vanilla Ice sell millions of records and two of the greatest vocalists ever in the rock genre it would be a giant mistake not to include this on the list. I can remember listening to my parents vinyl copy of Queen's greatest hits and literally bouncing off of the walls during this track.
Here is another great track with the word pressure in the title that would have fallen somewhere in the top 100 had I made a list that large.
Billy Joel - Pressure
