Wake Up
"Wake Up" is a pop song co-written and co-produced by Hilary Duff, Joel Madden and Benji Madden for Duff's fourth album Most Wanted. It was released as the album's first single in 2005.

Chart performance and video
In the U.S. it was released to Mainstream Top 40 radio on July 11, 2005, and it was the most-requested song on Radio Disney the following month. Largely because of high digital download sales, the single entered the U.S. Billboard Hot 100 at number twenty-nine in mid-August, the week's highest debut. It spent two weeks in the top forty and six on the Hot 100, and it also reached the top forty on Billboard's Pop 100 chart. In late October 2005 the RIAA certified "Wake Up" gold for its download sales. As of 2006, it is Duff's biggest hit in the U.S.

"Wake Up" was even more successful outside the U.S. It was released in the UK in late October and debuted at number seven, Duff's highest position on the singles chart there; it stayed in the top forty for six weeks. In Ireland it peaked inside the top five in its third week, and in Australia it reached number fifteen, remaining in the top forty for eleven weeks. Its success across most of Continental Europe was limited. In Norway it reached the top five, but it peaked outside the top twenty in the France (where it remained on the chart for nineteen weeks), Switzerland and the Netherlands, and it did not reach the top forty in Sweden, Austria or Germany.

The single's video was directed by Marc Webb, who had directed videos for The Used and My Chemical Romance. Duff said "I'm a huge fan of [the bands he's worked with], so I was really excited that he would direct my video. The [style] looks kind of grainy and it's a totally different look for me." It shows Duff leaving her home and journeying to nightclubs and parties in London, New York City, Paris and Tokyo (the cities referenced in the song's chorus). "[I]t just shows that no matter where you are, people want [to do] the same things: they dance and they party", Duff said. The world premier took place on Disney Channel. The video then aired on MTV's Total Request Live on July 15, 2005 and reached number one on the show's countdown on three non-consecutive days. After spending fifty days on the countdown, it was retired on October 6.
