The Wombats: 'Let's Dance to Joy Division' lyrics

The Lyrics
The lyrics to this track are pretty ambiguous. The use of 'irony' could be interpreted on various levels and the intrinsic links with joy division combined with the upbeat track confuses even more. Anyway, these are the ideas I've decided to stick with in order to apply moving image to the track:

'Let's dance to joy division and celebrate the irony, everything is going wrong, but we're so happy'

ok. here goes...

• celebrating the irony of dancing to joy division.
  
• everything's going wrong for joy division, but the wombats are going to remain happy.
• celebrating their realisation of how happy they feel when dancing to joy division

now, there are waaaay more ideas that could be extracted from this key line, but we've got to settle on a mere few otherwise we could go round in circles all day.

The other key line is:
'Let the love tear us apart, I found a cure for a broken heart'

• Surrendering, letting go, allowing things to go wrong, letting love be lost because...
• They've discovered the 'cure'; the happiness of dancing to joy division.
