There are so many counter-examples. I am instantly reminded of a childhood friend who was really into classical music. I don't think he arrived there working all the way back from present. I started listening to The Who because my dad had a CD of theirs in his car, which led to other classic rock. It had nothing to do with a backward time travel from whatever contemporary music I was hearing at the time. I think a lot of music learning happens more serendipitously like that, through friends, random encounters, etc. The historical research is definitely a part of it but this article way overstates it.
