None of this means that catalogue is dead, but it does need an overhaul if it is to retain relevance. Selling people nostalgia is no longer enough on its own (though of course a solid market still exists for selling digital remasters to aging rock fans). The Guardians of the Galaxy is a great example of how to make catalogue work in the current market. For young fans of the movie, the music is simply the soundtrack to part of their culture that just happens to be decades old. The music is given new cultural context for a new generation. This is the sort of thinking catalogue needs to thrive in the streaming era.
