Why do we always use that expression when we don't like a performer(s).
Invariablly the performer(s) are very good, but their style of music is not what we like. Then off we go spouting "he/she/them, are crap" when in actual fact, they are not crap, rather not our style.
The crap attitude can have an effect on audiences attending a concert. Whereas if you explain to a person who has never seen an act, what their style is and that they are indeed a very good act, but not your particular style. Then people can make their own mind up by going to see them.
How often have I heard somebody telling me an act is crap and then when I ask them why, they turn round and say "because so and so said so"
The Beatles were excellent and influenced music very much. To say they are crap is far from the truth. Maybe you don't like them, but to say they are crap!!!!
I don't like modern jazz, but that doesn't mean that the performers who do that, are crap. They are probably excellent. The problem is with me, becuase its not my cup of tea. In fact I only have one tune that I particulary like in the modern jazz scene, and that is Take Five - Dave Bruebeck.
