That seems to be a common trend on the internet (particularly on YouTube). To hate on any young sounding person (young enough to still be in high school) who's heard of a classic song first through a new film or video game yet would still shit on them (younger people) either way for listening to their own generation's songs.
Just read the comments in this youtube video link and you'll know what I'm talking about.

It's annoying and the older generation screwed the world up. Look at who is running for office.
