This really hits home for me. Back in my late high school / early college days I was obsessing over not only finding new music but being the first to recommend it to my friends.
Some professor in college made a comment once about how at around his mid/late 20s he stopped putting much effort into finding the latest and greatest bands, and just kind of got comfortable with what he already knew and it seemed to be a common thing among his peers.
I vowed to never let this happen to me, but here I am at 29, comfortably listening to most of the same music I did in college, with little new addition over the past 3-4 years.
