I like to track album sales performance on iTunes charts. And I've noticed that since the movie and soundtrack of GOTG was released, two and half months ago, albums by 70's era rock acts have performed very well on iTunes charts. Now some of this may be due to streaming services skewing toward younger audiences. But classic rock, which I include anything from Fleetwood Mac to Led Zeppelin, has really begun to shine on the charts. There's even an album titled "21 Classic Rock Favorites" that performs well on the charts.
Maybe this is similar to the affect "Saturday Night Fever" had on disco nearly 40 years ago- but to a much lesser degree.


Great movie, great soundtrack. GOTG was obscure as far as Marvel goes. I remember reading an issue in my dentists office, years ago.
