The Old Habits Stay Strong

I was thinking about the various algorithms and what-not in my media players, and I guess my tastes are pretty obvious: classic rock, hard rock, some spacey folk and mood music, bluesy tunes...

...and I think about what I was listening to in adolescence/early adulthood (plus the music I was making), and not much has changed. The digital overlords apparently are aware, judging by the "suggested content".

Maybe I should be concerned...?
