Ingarbugliato means 'tangled up' or 'muddled'. It's a vivid and somewhat uncommon word that paints a clear picture of confusion or complication.
In the song, the lyric "Quanto ti sei ingarbugliato nel pensare che ti volessi male" (How much you got tangled up in thinking I wanted to harm you) uses this word to describe someone's mental state, highlighting their confusion and misinterpretation of the singer's intentions. It's a more evocative choice than a simple word for 'confused'.
"IL BENE NEL MALE" is Madame's raw account of running back into an ex after a long time apart, and finding out nothing really changed. She hoped for a simple "I missed you." Instead she gets excuses, talk, and the same push and pull that wrecked things the first time.
The title, "the good in the bad," is the whole song in five words. Madame keeps flipping the phrase, good and bad, good and bad, to describe a love that never lets her feel one without the other. She calls herself the worst mistake she ever made and, in the same breath, calls him proof that people repeat their mistakes on purpose.
By the end she admits she gave everything and kept nothing but regret, while he walked away carrying the good parts. It is a song about loving someone who only ever lets you keep half of the feeling.
