That's why it's called perspective. The way you picture something or hear it cannot be the same way another person will picture it. There's nothing like bad songs, just that your differences are not similar with another person.I would've have said that there are bad songs, but when I have come across people vibing to songs that I wouldn't play on a normal day, I came to the conclusion that there are definitely no bad songs. It is all about picking what you enjoy.
I totally get where you're coming from. Music is so personal, and what clicks for one person might not for another. It’s all about finding what resonates with you, even if it's different from what others enjoy.I would say there are such things as bad music but it all depends on the person listening to music. While some could enjoy a song, others might not and could call it bad music instead.
For example, I would say that heavy rock and heavy metal are bad music but someone else could say that it is great music.
