Master of the Strings

I have been learning how to play the guitar. The instrument seems quite simple but it demands a lot of energy and exercising. It's not easy to play the guitar, I have learned it. The reason why I'm putting much effort in the practice is because I love metal and rock. Metallica seems to be an old band who's songs are still being played and listened to. One of its famous songs, Master of Puppets has me do something, at random lately. The title of the song is strange. It seems to be connected with the world today. There are masters who posses power to rule the earth. They hold the strings of millions of people. People are treated as if they are puppets but my interpretation of the title is quite different. I presume the guitar player to be the master of the strings of the guitar, and the guitar, the puppet. Thats all folks.
