what is the difference between good and bad music


my friend says rap is bad music. another friend says mahler is a terrible composer.

is it all subjective, i.e., a matter of opinion ? or are there standards which can distinguish good from bad music, however one defines these terms ?

if there are standards, can one specify them or refer me to a source ?

Mr Tennis, Your inconsistency detector may need recalibration. Same POV from my direction except I used a different manner of expressing it.
hi redkiwi:

one person's emotional communication may be another's non communication.

if you and i listen to the same music, you may react emotionally and i may not. is the music bad or good ? or you may react emotionally to music one time and not another time.

your reaction emotionally is more a matter of your emotional state than the music you are listening to.

if your are not receptive to the music then there may not be an emotional reaction to any music.

again, do you like the music is more important than do you react to it.

i may react emotioanlly to a piece of music but still not like it for other reasons that have nothing to do with emotions.

i respect your perspective, but have yet to be convinced that quality of music, unfortunately is at the whim of the listener.

if you want to point to the intrinsiic qualities of music that signify quality it is necessary to point out what they are.

if instead you want to refer to a reaction to the music, there are many reactions that can be viewed as favorable to the listenet besides an emotional response.

You sound like you appreciate stimulation. I hope we've been of some help in that regard. :-)
