In an interview, the singer of The Showdown said something to the effect of, "All these new 'screamo' acts are full of little boys that look like they're afraid to be in their band." Yes.
I can appreciate good lyrics, but if you can't keep pitch, you probably shouldn't be in a band. Chris Cornell comes to mind, total studio job. Saw him live, my toddler can keep a tune better than he can.
Onto acts who, despite their ability to maintain pitch, are unable to otherwise redeem themselves.
Jewel
Hanson
Fergie
Gwen Stefani
Madonna
Huh. All girl acts (save for Gwen Stefani). Never figured myself for a misogynist.
