I can think of at least four well known tracks by the Black Eyed Peas (Where's the Love?, Shut Up, Hey Ya and Let's Get it Started). No offence, but I don't know what you're on about.

Maroon 5 have had several big tracks. This Love, Harder to Breathe and She Will Be Loved

Franz Ferdinand have had at least two reasonably successful follow-up singles.

Gwen Stefani as a solo singer may not last long, but in No Doubt there's no way you can call her a OHW.

Bowling for Soup have had a few well known songs as well, and the Killers have a second single that seems to be getting a bit of airplay.

Dunno about the others, cause I don't know much about them.

Eric Prydz. Now THERE'S a one-hit wonder...
