J.Lo, most of the time, chooses good singles.
I think her only mistakes are HYD (I'd choose Step into... or Cherry pie) and BILY (Loving you or maybe The one instead).
Madonna with most of her albums.
Except with Ray of Light (). She should've released Sky Fits Heaven instead of Drowned World/Substitute for Love and Swim instead of Nothing Really Matters.
Korn were doing good until "Politics"...what the **** was that about? Totally screwed over "Love Song"/"Throw Me Away".
nine inch nails released "The Hand That Feeds", "Only" and "Every Day Is Exactly the Same", which were all good moves, seeing as they each had multiple weeks at #1 on Modern Rock.
