ok, here we go...:
(this is based off of the tour, not the album)

circus: good opening as well as the intro..it gives u a feel that there is much to offer throughout the concert (gives u chills too)

piece of me: very good. with the cage and everything..it really shows the meaning of the song (being in the cage restricts the dancers from getting her-hence, "u wanna piece of me?")

radar: good song in general, but not really exciting during the concert. if it was performed at a miley cyrus concert it would be "scandalous" but the regular dirty dancing is done during britney's concert.

ooh ooh baby / hot as ice medley: this is one of my favorite parts of the concert: i have grown to love them combined but hot as ice is definitley has the best entrance (all the magic tricks are really cool, too).

boys: interesting. boys of course surrounding britney with their tiny pink briefs. it is funny and cool with all the bikes and army costumes.

if u seek amy: like radar. just regular dirty dancing.

me against the music: cool because it is based off of bollywood (indian) style music and dancing. the costumes are cool too.

everytime: a ballad that is cool because she sings it in an umbrella that is lifted up from the stage.
