Money (That's What I Want)
The tour set list featured most of the songs from the "Doo-Wops &amp; Hooligans" album, as well as two covers of songs by other artists on which Mars had been a featured vocalist, B.o.B's "Nothin' on You" and Travie McCoy's "Billionaire". It also typically featured four or more covers of older tracks, which differed from one concert to another. Among these were Barrett Strong's "Money (That's What I Want)", The White Stripes' "Seven Nation Army", Aaliyah's "Rock the Boat" and two Michael Jackson songs. On one of the tour's European legs, a song recently penned by Mars, "It Will Rain", was also performed, featuring guest artist Skylar Grey.
