I agree that Rihanna went from being one of many up&coming r&b babydivas to a deserved megasuperstar but it's just not true that she had one good song per album - Music Of The Sun is a long-time favourite of mine, A Girl Like Me is kind of patchy but has even higher highs than MOTS. Good Girl Gone Bad might actually be my least favourite Rihanna album. But none of them are bad albums except in a "beyond the great tracks, which comprise most of the album, there is some filler" sense.
