• The lead single from Islands is a cuss-filled track, which is unlikely to be played on daytime radio in an unedited form. Frontman Tim Wheeler said:
  
  "The day I wrote 'Buzzkill', it took me a while to stop laughing cos it's so fun, dumb and full of unnecessary swearing. We used to know a band called Buzzkill in Belfast in the '90s and I think their name has been in my mind for all that time wanting to get into a song."
• The song features The Undertones' Damien O'Neill and Mickey Bradley on backing vocals. Wheeler explained:
  
  "Having seen The Undertones playing a couple of times recently I was guiltily thinking how much the backing vocals I'd written for 'Buzzkill' were mimicking their style. So I thought it would only be right to ask Damien and Mickey to sing on it and we were honoured when that they said yes, despite all the filthy cussing. It's a fun song and will hopefully ignite a few mosh-pits for us this year."
