Ugh, Bad Girl only gets more gut-wrenching and heartbreaking as time goes by, doesn't it? The lyrics are such a stroke of genius, they express the protagonist's self-hatred and crippling lack of self-confidence so well. Drowning out those feelings ("I don't wanna feel blue") by indulging in bad behaviour, hiding parts of who you are and being convinced that people would be disgusted if they knew "the real you" ("I always feel the need to hide my feelings from you / Is it me or you that I'm afraid of?"), wanting to course-correct but failing ("I tell myself I'll show you what I'm made of") which results in even more self-loathing ("I know I don't deserve you") ... There is just so much to unpack here. She must have been in a pretty dire state, or be an insanely empathic person, or both, to have been able to write that song. And her mournful delivery! People often rat on Madonna's vocals but there are very few singers who are more emotive than she is, and Bad Girl is a prime example of that.
In short: a triumph of a song - why don't we talk about it more?
Yes, the video is iconique, but I'm going through some stuff and wanted to focus only on the - relatable - song as such.
