8. Black Eyed Peas
Black Eyed Peas members will.i.am, apl.de.ap, and Taboo weren't always futuristic and/or successful. It took years as backpack rappers, a record deal with Eazy-E, a few name changes, the departure of a handful of lesser-known members of the group, a drastic shift in sound, and most importantly the addition of singer Fergie, to send the band into the stratosphere.
After their first two albums made it all the way to "eh" on the charts, the Black Eyed Peas were on the brink of being mere mortals. Will.I.Am, in an attempt to get proper backing from Interscope Records, agreed to label head Jimmy Iovine's call for a female member, and took Fergie in.
BEP's next album, Elephunk, was a smash, with "Where is the Love?," "Shut Up," and "Hey Mama." Monkey Business gave us "Don't Phunk with My Heart," "Boom Boom Pow," and "My Humps." In virtually no time, the Black Eyed Peas went from nowhere to everywhere, and stayed there. Will, Ap, Taboo, and Fergie have since created group albums, solo albums, car ventures, clothing lines, headphones, video games, schools, foundations, and a concrete definition of selling out.
