Don't give up. There are those who still can discriminate although they are fewer. The music world is significantly segmented more than it has ever been but good music transcends. If you and others give up then all is lost. With most listening to crappy MP3 files and with a lot of "pop,rock,whatever" music devoid of melody with Philip Glass repetition it is mostly forgettable. However there are some really good young artists writing and recording new music. So I have hope for pop music. As to live music concerts that's another issue. Too loud!. Some groups can't sing and depend upon the beat and sound volume.
I think the audience today has not been exposed to quality so they can't identify bad music and performances. Just my view. So keep exposing them to something better.
