This is a playlist I created two years ago just after the disastrous 2015 election. Seemed appropriate to reshare it now.
Tracklist is:
George Hardy The Land Song
Tom Robinson Band Winter of 79
The Bonzo Dog Band No Matter Who You Vote For, The Government Always Gets In
David Steel I Feel Liberal Alright
Steve Earle Jerusalem
Buffalo Springfield For What It’s Worth
The Imagined Village Hard Times Of Old England Retold
Klaus Nomi After The Fall
The Millennium It Won’t Always Be The Same
Pulp Common People
The Kinks Dead End Street
The Specials Ghost Town
Woody Guthrie This Land Is Your Land
Sci-Ence! Justice Leak! 
Excellent list. I must admit I have not felt so angry or down since at least 30 years ago. Inspired by your Specials track may I also suggest The Fun Boys Three with “The lunatics Have Taken Over The Asylum”
