Enka music had been supported by only middle-aged and elderly people and it became harder for singers with powerful voices and outstanding vocal ability, such as Saburo KITAJIMA, and unique singers with distinctive quality of voice and vocalization, such as Shinichi MORI, to display their talents as people had valued easy songs for amateurs to sing in karaoke, and thus enka music had less TV exposure.
演歌が中高年のみの支持に限定されてきたことや、素人がカラオケで歌いやすいことが尊ばれ、北島三郎のように圧倒的な声量や歌唱力を誇る歌手や、森進一のように独特な声質と歌唱法をもつ個性的な歌手が実力を発揮しにくくなり、テレビへの露出が減少した。
