Can popular music achieve a genuine political change?

In my opinion the answer to this is no, certain popular music may have political messages but will only appeal to some people and not others, and if there was a song with a strong political message it would need maximum promotion, this would only be achievable with the support of a major label, and therefore if a artist did decide to release a song with a political message such as a anti-capitalist one, it would be contradictive as the artist would be making money for the major record label and therefore for a capitalist society, also the chances of a major label letting a artist do this are very slim, possibly with a independent label which lets artists have freedom of creativity will let you this but will not have the means to promote it as good. Either way a song would not be able to gain a political change, too many things in society that come before music have to change first.
