Any band whose music receives seemingly endless radio play, that does not have the skill, talent, or time investment traditionally required to gain such promotion. Generally these bands and their music have been manufactured by a record label to appeal to the largest audience possible. Soul, innovation, experimentation, emotion, honesty and strong beliefs are sacrificed for fear of alienating potential customers. A product rather than art, whose success is purchased and engineered rather than earned.
Do people actually listen to Nickelback? They are radio trash.
Lady Gaga openly admits to being radio trash... She calls herself "the fame monster". Who would want to be that? Who would support that?
