4. Make The World Move (Feat. Cee-Lo) - A barn-storming party anthem emceed by the two "Voice" coaches, "Make The World Move" is backed by a brassy, big-band arrangement that would make the song an easy fit on 2006's 1940s-inspired "Back To Basics." But in the hands of producer Alex da Kid, there are plenty of modern flourishes to make it a hit for the 2010s.
5. Your Body
Max Martin songs aren't exactly a vocalist's best friend, favoring giant melodies and hooks over histrionics. But leave it to Aguilera to find ways to inject her personality into this midtempo single, which really doesn't peak until the singer growls on the bridge "I think you already know my name."
6. Let There Be Love - Another Max Martin-Shellback team-up, "Let There Be Love" goes straight for the clubs, riding a propulsive beat and chewy synths straight out of Martin's recent hits with Usher ("DJ Got Us Fallin' In Love Again," "Scream"). Aguilera seems keenly aware that the song's overly familiar formula that leaves little room for personality, which is why she spends the last minute wailing all over the place.
7. Sing For Me - If "Army Of Me" is this album's "Fighter," then "Sing For Me" has aims of being a "Beautiful" for the next generation of Aguilera fans. With a thunderous chorus where Aguilera brings ironic depth to lines like "'Cause when I open my mouth / my whole heart comes out," "Sing For Me" is a gift to diehard Aguilera fans.
8. Blank Page
Aguilera's previous collaborations with Sia were some of the most underrated tracks on "Bionic" ("You Lost Me," "I Am"), so it's nice to see the two reunite for "Blank Page," a song that will likely reach a much larger audience thanks to the elevated profile of both performers. A fiery piano ballad, "Blank Page" offers to wipe Aguilera's slate clean while trying to reconcile an old romance ("if I could do undo that I hurt you / I would do anything for us to make it through.")
9. Cease Fire - This is around the time where the military analogies start to wear thin. "Cease Fire" finds Aguilera "alone on the frontlines," asking her lover to "stand next to me" and "throw down your weapons." A litany of other war references follow suit, unaided by a chorus that never takes off.
10. Around The World - If "Your Body" finds Aguilera ready for love-making right here, right now, "Around The World" sees her looking to add a few passport stamps to the equation. Sadly, the second-verse reference to "Lady Marmalade" remains one of the few moments of fun on this otherwise tepid track.
11. Circles - The biggest surprise on "Lotus" comes from the blaring, 90s riot-grrl chorus on this anti-haters screed, where Aguilera invites her haters to "spin around in circles on my middle middle finger," while mini-Aguileras chant words like "round and round" and "mother****er" in childlike voices. Way more fun than "Shut Up" on the deluxe edition, "Circles" is Aguilera at her most unapologetic and all the more delightful for it.
12. Best Of Me - Once again on the defensive, Aguilera shows signs of vulnerability on this powerful ballad before the military drums kick back in for the final chorus. A hopeful spin on a time where she was "knocked down and mistreated," "Best Of Me" sees Aguilera putting the events of 2010 behind her.
13. Just A Fool (Feat. Blake Shelton) - You know how so many of the duets during the battle-rounds on "The Voice" just sound like two people shouting melodically at each other for three minutes? That's what Aguilera's giant, bloody stab at country soul with Blake Shelton sounds like, rattling the speakers and all the whiskey off the bar with an epic chorus that only increases in volume as the song progresses. In case you forgot that Aguilera was a singer with a capital S, this song is one last helpful reminder.
