Obligation and Advice in the song “Should I Stay or Should I go?: Have (got) to / Should

With this activity you can learn the use of the modal verbs HAVE (GOT) TO and SHOULD:

• We use SHOULD to express ADVICE.
  
• We use HAVE TO to express OBLIGATION in written and oral communication. But we usually use HAVE GOT TO in oral communication, for example in song.
  So it's very common to find HAVE GOT TO in many different versions, as they appear above:
  
  • have got to = 've got to = got to = gotta
