"Move Along" was written by Nick Wheeler and Tyson Ritter. Wheeler explained that the song was is "[a]n anti-suicide message song about believing in oneself and persevering in the face of problems". According to Wheeler, they wrote the song at a time "[w]hen we were at our wits' end wondering if we were ever going to get to make a second record. Our manager and our guy just kept saying, 'Keep writing, keep writing.' All we knew was, hey, man, we wrote 11 songs and that's all we had to our name when we made the first record."
Ritter went on to say, "Thankfully [our manager] pushed us to our wits' end, because the last two songs we wrote for our second record were 'Move Along' and 'It Ends Tonight', which were both top ten hits. And it actually became pretty easy writing follow-up hits once the juices started flowing."
The song received mostly positive reviews from music critics. Punknews.org referred to the track as an "excellent song" and "The perfect predecessor as their last single 'Dirty Little Secret'", while About.com reviewed "Move Along" as "another slice of catchy pop-rock this time attached to an uplifting, encouraging message. There is little lyrical depth here, but that's not necessarily a bad thing. The All-American Rejects will win no awards for innovation with this single. However, for energetic pop-rock radio fare, 'Move Along' nicely fills the bill".
Contactmusic.com were negative towards the song, saying "'Move Along' unfortunately lacks any originality, it sounds like so many other songs released in the past five years or so. They are a poor man's Green Day - even after listening to the song a few times, it still sounds the same; it doesn't seem to get any better", while Entertainment Weekly commented "The title track launches the band beyond frivolous puppy-love-powered pop. The grinding guitars, pulsing drums, and arena-ready rawk refrain turn 'Move Along' into an anthemic gem that, while seemingly still about girls, is truly something special."
"Move Along" debuted in the top 50 of the U.S Billboard Hot 100 and remained there for a total of 39 weeks, eventually reaching the spot of #15. It later reached the top 5 of Billboard's Hot Digital Songs and Hot Adult Top 40 Tracks charts and reached #7 on the Hot Canadian Digital Singles chart. This is the band's most played song on alternative rock radio stations despite not entering the Alternative Songs chart as of modern rock radio station, KROQ-FM was the first radio station to play this song along with the other singles from the album.
As of March 2009, "Move Along" has sold over two million digital downloads in the United States.

The music video for "Move Along" was directed by Marc Webb and shot in December 2005 in Los Angeles and was released a month later on January 18, 2006. It revolves around lead singer and bassist Tyson Ritter, standing absent-minded going through a series of personal problems (e.g. relationship issues, job stress, losing a football game) as the scene jump-cuts quickly with him standing in the same position while wearing various kinds of clothes and situating in different locations.
The quick-cut style of the video was inspired by Marlowe Gregorio, who created a video tribute to the song and posted it on YouTube before production on the official video began.
