the reason I stop listening to those types of songs is that the music industry is corrupted and full of puppets.
多重复合句,没有错误;其中主句是 the reason is that,具体结构如下:
主语部分:the reason I stop listening to those types of songs
【主语核心名词】the reason
【同位语从句】I stop listening to those types of songs (由于先行词是 reason 自身就表示原因,因此可以将其视作连词,why 或 that 之类的连词常被省略,这样句子用词更加简洁 )
谓语部分:is that the music industry is corrupted and full of puppets.
【系动词】is
【表语从句】that the music industry is corrupted and full of puppets.
