There do not exist fix patterns that define good or bad music. Anybody has a taste for music and has preferences for music styles, artists or composers. A few generations ago, the social class influenced strongly on the music preference of a person; nowadays music is a product of a huge industry where often commerce is considered more important than quality. A good example is the Pop-Music, which is an abbreviation of popular music; this music style needs frequently new songs because they are often so simply composed that one gets bored hearing them over and over again. One of the ways how music is perceived has to do with one’s state of mind.

The state of mind of a person is perhaps the most important factor that defines good and bad music; as a result, it explains what music someone is listening at a given moment. In real life most individuals have more than one music preference, so is it common seeing that somebody likes Rock-Music, but listens also to Classical-Music or to Jazz. Lets say a driver, who is used hearing classical music in the car, might consider Folk-Music as bad when hearing it unexpectedly in the car’s radio. Music considered bad by the driver has not to be bad technically; in fact, a large radio audience might enjoy it. In short, the state of mind is an important factor how an individual perceives music, but it has nothing to do with the overall quality of this piece of music.
