It's a minefield when it comes to choosing the soundscape to your party conference.
Do you go for chest-thumping patriotism? Toe-tapping optimism? Or dour predictions of doom?
Whatever the mood you are looking to set, two rules apply. First, get permission from the cool rockers whose shine you are hoping rubs off a little on your party. Second, always, always read ALL of the lyrics.
It's been an issue that's plagued the Manic Street Preachers, whose 1998 single 'If You Tolerate This, Then Your Children Will Be Next' was first appropriated by the BNP.
Now the band are said to be taking legal action against the English Defence League for using their anti-fascist song in the background for a video ahead of a protest against "radical Islam" in Birmingham.
The song, written about the Spanish Civil War, even includes the line: "If I can shoot rabbits, then I can shoot fascists".
The Republican Party in the US has often born the brunt of confrontations with pop and rock stars. John McCain and Mitt Romney were basically banned from using anything earlier than 15th century Baroque by a landslide of lawyers' letters from Foo Fighters, Jon Bon Jovi, Jackson Browne, K'naan, Twisted Sister, Heart and Katrina and the Waves.
Some politicians, like William Hague and David Cameron, have been banned from even saying they like certain bands by the band members in question.
