This is dumb.
Most of the songs are categorized according to their topic, but some of them are about the film technique that accompanies them ('montage'), some are about the authors political hangups ('problematic'), and 'It's dancing time' doesn't seem to have any unifying theme besides being upbeat. Life lesson time is strange, it's unclear why you would put 'Make a man out of you' there and unclear why it doesn't go in the bin with the rest of montage.
The core formula/sometimes good songs/rarely good songs division is completely unclear sing 'rarely good' cuts across most of the categories.
I could go on, but I'm trying not to be as autistic as whoever made this.
