I found out today that, because of the music from Vol. 2 Guardians of the Galaxy: Awesome Mix Vol. 2 (Original Motion Picture Soundtrack), my 10-year-old son Samuel is into ‘Mr. Blue Sky’ from Electric Light Orchestra. 

‘Mr. Blue Sky’ is on Out of the Blue, Electric Light Orchestra’s seventh studio album, released in October 1977. Written and produced by ELO frontman Jeff Lynne, the double album is among the most commercially successful records in the group’s history, selling about 10 million copies worldwide.
