Justice have two fantastic records.
D.A.N.C.E and Never Be Alone

The rest of their stuff is generally woeful. Their DJing is very average.

However the atmosphere was unbelievable, inexplicable actually. What is all the fuss about? They look cool but offer very little. The crowd acted like they were at a Take That concert in 1994.

Students and drugs = Sweaty pandemonium.
Here is a the best song I have heard/bought today by miles...
Gym Class Heroes - Clothes Off Ft Fall Out Boy?
