It's called buying songs from great songwriters and hiring session musicians to play the parts, and getting some hot synth/sampler/remixer dude to loop and mangle things.
Oh yeah... and Antares auto tune or TC Voice Prism on the vocals so they are in pitch. Also to make them sound 'beefier', drown with a few 2 and 3 part harmonies (automatically generated on your pitch shifter) and add a ton of reverb and you're all set.
Optionally you can aim for the Ricky Martin/Latino percussion overdubs from hell.
