Something I have noticed is Britney dances throughout her songs which causes her to hold back a little energy. While J.Lo stops the song to add in a breakdown... There both good at dancing, however Britney lacks the energy. J.Lo gives it her all since she only dances at one time. Like In Get Right, I'm Real & Love Don't Cost a Thing, theres a minute where it's just str8 beats.. However with Britney she dances throughout the song like in Me Against the Music.
