Songfacts®:

• Panic At The Disco frontman Brendon Urie grew up in Las Vegas. Here he evokes his younger days in Sin City while alluding to some personal troubles. The song title plays on the name of a 1964 Elvis Presley movie and song.
• In the first verse, Urie struggles to create art, and when he does, someone pilfers it.
  
  Someone did me wrong, stole my favorite song, yes, it really hurt
  
  Urie may be referencing former POTUS Donald Trump using Panic! At The Disco's "High Hopes" at a re-election rally in June 2020, when Urie was very much anti-Trump.
• The second verse concerns a hacking incident. We do not the details, but Urie likely highlights this to make a point about the lack of truth on the internet.
• Having grown up amid the glitz and seediness of Las Vegas, Urie has experienced everything the city offers. On the chorus he's hooked up with a prostitute who warns him that the pleasure he seeks is momentary and ultimately the city will have its revenge on him.
  
  Shut up and go to bed
  She said "Viva Las Vengeance"
• By the end of the song, Urie is distressed over all the criticism dished out to him, but he will continue to make music.
  
  I'm being buried alive
  Didn't wanna kill the DJ
  But it can't hurt to try
  
  Urie could be referencing The Smiths' "Panic," where singer Morrissey repeats the lines "hang the DJ" and "hang the blessed DJ."
  
  As a sidenote, Panic! At The Disco didn't take their name from The Smiths' song, despite its references to "panic on the streets" and "burn down the disco." Rather, they named themselves after a line in Orange County pop-punk outfit Name Taken's 2004 track "Panic."
• This bombastic slice of power pop is the lead single and title track of Panic! At The Disco's seventh studio album, Viva Las Vengeance. Urie recorded the record using a tape machine in Los Angeles alongside his producer Jake Sinclair. "Viva Las Vengeance is a look back at who I was 17 years ago and who I am now with the fondness I didn't have before," Urie said. "I didn't realize I was making an album and there was something about the tape machine that kept me honest."
• Frequent Panic collaborator Brendan Walter ("High Hopes") directed the campy video. The clip starts with Brendon Urie playing piano with an accompanying band on a '60s-style TV variety show. "Welcome to Viva Las Vengeance," the caption accompanying the visual reads. "This is the tale about growing up in Las Vegas. It's about love, fame, burnout and everything that happens in between."
  
  As the song progresses, the instruments attack Urie onstage. He continues to perform, even as his piano eats him alive.
• Urie previously paid tribute to his Vegas roots on Panic's 2013 album Too Weird To Live, Too Rare To Die! He wanted its "Vegas Lights" track to become an anthem for the city.
