text: Peter: I'm making a playlist for tonight
  Peter: What music do you prefer: the 70s or 80s?
  Jeff: The 70s of course
  Laura: no! The 80s are pathbreaking
  Laura: new genres, electronic music etc
  Jeff: but the 70s were the most joyful after war
  Jeff: I love disco from the 70s
  Molly: abba, the Beatles
  Jeff: but also Led Zeppelin
  Peter: so it seems I should do some mix of the 70s and 80s
  Jeff: why not? like the biggest hits
  Peter: good idea
  Peter: and we won't run out of music
  Laura: no way
target: Peter's making a playlist for tonight. He's going to do a mix of the 70s and the 80s.
