the problem on most of their collaborations is her lame lyrics, not his music. She wasn't writing music because she'd run out of ideas, or was doing too much coke, or whatever. She got lazy. In the early days she'd try to create her own music. Then she got too famous and lazy. So she slapped a lot of messy sloppy lyrics over his music. I wouldn't blame him for things like "take a moment and think for a minute for a moment for a minute"
