Question: I am interested in songs by the same composer/ song writer that talk about political ideals affecting the country's masses. May I know some?

Answer: 
While one could certainly argue that all music (like other forms of art) is subject to interpretation, even in spite of the artists' original intent, there are lines in "Master of Puppets" that are hard to interpret as being about anything other than drugs:

*Taste me you will see
More is all you need* (i.e., addiction)

*Needlework the way, never you betray* (i.e., injecting drugs intravenously)

*Chop your breakfast on a mirror* (i.e., chopping lines of cocaine)

*Fix me!* (i.e., getting one's "fix" of a drug they're addicted to)
Master of puppets - it is not about drugs. They used drugs to speak up.

Master of puppets talks about the person who is above you. Your parents, teacher, boss etc. You can't do nothing about it.

Musicians speak their mind out. Master and puppets is truth. One plays a role as master and a puppet.
