I want to know the answer to the following question:
Pachelbel's Canon has influenced popular songs since what decade?
All the background I'm provided with is that "Numerous examples show influence in the opposite direction, including popular songs based on classical music, the use to which Pachelbel's Canon has been put since the 1970s, and the musical crossover phenomenon, where classical musicians have achieved success in the popular music arena.". Is that enough to answer the question?
Answer: yes
