Preach sis. Only the old generation listens to her, and they only listen to her old music. With Britney, you can listen to her old albums and new albums and it will still be revolutionary. Listening to Madonna's old discography sounds out dated, and it doesn't help she doesn't bring anything new to the table.
Madonna's early albums have aged better than Britney, and they're ~15 years older.
