15. Mick Jagger
Funkiest Jam: The Rolling Stones "Beast of Burden"
Leaving aside his phenomenal career as front man of the world's greatest rock 'n' roll band, Mick Jagger belongs on this list for two big reasons. Maroon 5 and Ke$ha are the world's foremost authorities on funk. Maroon 5 wrote a song about Mick Jagger. Ke$ha only likes dudes who look like Mick Jagger (or else to the curb they are kicked!). This selection is pretty straight-forward.
