Great article... I think I'm at the opposite end of the writer's spectrum, though, despite the amount of time I spend listening to music. Since I buy music in CD/SACD form, my library is strongly constrained by budget, so I don't listen to as much new music as I should (my collection is also strongly-weighted toward audiophile recordings, which generally means that it is extraordinarily conservative).
Instinctively, I know this is wrong because many of my favorite albums have been somewhat random, rather than planned purchases. Still, that Mobile Fidelity SACD of Santana III has my name on it.
Even with those caveats, I have no excuses with access to free Spotify, internet radio, YouTube, etc. We are living in an unprecedented age of musical accessibility, and I am not one to complain.
