For ages music has been exploited by politicians during rallies and major gatherings. From the most popular to the unknown artists they have been used somehow as crowd drawing, fillers or as a tools to build interest.
So my question is how far has an artist has to "play" along? Should it be those artists that subscribe to the political party policies or it should be just a job as usual for the artist?
It is well known that once an artist has served the interests of these politicians or parties they are discarded just like that.
I would say treat your music as business and avoid being used as a tool unless you subscribe to the party.
The danger though of affiliation is that as an artist you might lose your rights of freedom of speech and end up being a puppet. I take it that a true artist believes in the freedom of thinking and freedom of speech. An artist's work is to be a social commentator but not as a political party tool.
