I predict that it will either be Heavy Disco or Brucknerian Power-Salsa. That, or more hit-factory recycling of radio-friendly schlock that wasn't especially great the first three or four times. However, in a cruel twist of fate, overt corporate sponsorship will reenter the fray.
Soon, many radio, benzene, and concert promotions companies will form into one massive entertainment combine, Allied Benzene, and the studios will start releasing albums like "Six Carbon Shuffle" by the band Known Carcinogen. Not to miss out, hated rival, National Cyclohexane, will force Highly Flammable to cut the disc "12 Hydrogen Road." Eventually, everything will fall apart and the sound of two rocks being smashed against one another will be the industry's idea of a "crossover hit."
