They stated that the "prime" ages for being exposed to new music is 14 to 21 and after 21 interest drops off until 35. After 35, 95% of people don't like new music, no matter how "good" the band is. By "good" in this context, I'm assuming they mean "like other music you already like". Much commercial radio, if not all, uses this underlying assumption as its basis for programming. They call it something like the "release plus 20" formula, meaning that people born 20 years before the songs release are the primary consumers.
I'd had a discussion about something similar with hagbardc just last week. We were both decrying how someone we know listens to the same music he listened to in high school. hagbardc says he never listens to old stuff any more while I have a tendency to revisit older music from time to time.
I was also thinking that almost everyone I consider a friend falls into that 5%. Not exactly, as many of you (and those not on LJ) aren't 35 yet, but you're trending towards the 5% by continuing to be interested in lots of new music. Do any of you only listen to the "good old stuff from HS and college" or am I correct in my assumption that you want to be exposed to new bands and songs?
