Having a good collection of MP3s in an iTunes library can turn us all into compilers. One possibility is an 'Agit Pop' CD. Something that straddles the fantastic pop of the late '70s and early '80s, and the spikier post-punk stuff.
So far, it's got these tracks:
At home he's a tourist - Gang of Four
Ghost town - The Specials
We are all prostitutes - The Pop Group
London calling - The Clash
Stand down Margaret - The Beat
Religion - PiL
The lunatics have taken over the asylum - Fun Boy Three
It could have any one of half-a-dozen tracks by The Jam and there are plenty of additions that could be made from The Clash or The Specials discography. It could - controversialy - include something by Sham?
