Just like in the 'Dani California' video by the Red Hot Chili Peppers, in this video for 'All I want' by A Day To Remember features other bands. However, this video isn't a parody but a homage and it brings together many artists of the same genre. As there are other bands/artists such as Pete Wentz (from Fall Out Boy), Pierce the Veil and Bring Me The Horizon featured interacting with their song, ADTR has increased their audience and the credibility of their song. The other bands may have publicized the fact that they were in the music video therefore exposing their fans to the music of ADTR which is in ways similar to theirs. This is a clever marketing technique to use in terms of selling a video and in turn selling a song.
The illustrations featured over the video, the lyrics and lines around instruments, are an element featured heavily in the early pop-punk videos. It resembles writing in someones diary and drawings that people may do over their work at school, again this relates to the audience as it is something that they may find themselves doing a lot.
An observation that I had mad is that some of the lip syncing was out/the wrong words seemed to be being sung, this however could be because it wasn't the band singing but people from other bands who probably didn't know the song well enough before they were asked to mime it.
Lead guitarist Jeremy McKinnon stated that the song is about "taking chances, and doing what you think is right regardless of what people might think. To be honest, whats more important? Live life, and be happy with yourself".
