There is this song I have been looking for forever but I can only remember the music video. The band was making a music video and their producer was giving them three steps to a successful music video which included commercialism, girls(I think), and stealing another persons idea at that part the guys in the band were dressing up in lady gaga and Katy perry. Can you please tell me the name of the song?

Pretty sure you're looking for this:
