(to let one's hair down)
Corrine Bailey Rae, Song:
Put your records on
Girl, put your records on, tell me your favourite song
You go ahead, let your hair down
Sapphire and faded jeans, I hope you get your dreams,
Just go ahead, let your hair down.

Let's Dance to Joy Division 

Song that apparently upset already depressed Joy Division fans. Kinda pathetic if you look at SongMeanings and similar sites and see their reaction to an indie band mentioning their brilliant band in a song. Oh, the song's also by The Wombats.

Teenager: Hey, did you hear that song Let's Dance to Joy Division? I love it!
JD fan: Fuck you, you don't have the right to listen to that kinda stuff... you little teenybopper.
