It's the chicken and egg question. Which came first? In this case, do young people not listen to the radio because the music of their generation is not being played? Or because young people don't listen to the radio, even alternative and active rock stations must rely on 30 year old music for more mature listeners?
Do you remember how it was when you were young and radio was the only place to hear new music? You'd hear a new song -- an amazing new earworm - and you'd hope the DJ would announce the title and artist so you'd know what it was. Then, if you wanted to hear it again you would have to leave the radio on all day and maybe you called the request line to ask the live DJ to play it. Some of you would also sit there with the cassette tape recorder cued up waiting to hit record as soon as the first few notes started up.
That was music discovery and acquisition then. Does radio today hold the same importance to young people?
Well today, music is everywhere. When you hear something you like, if the title and artist aren't already displayed in front of your eyes, you can Shazaam it. Then, instead of waiting all day for it to be played on the radio, you can instantly stream it or find it on YouTube. Instead of spending weeks compiling a cassette tape of favorite songs with the intros and extros cut off, you can instantly build, edit, and re-edit playlists on your chosen streaming platform.
No young person has to sit through a bunch of songs they don't want to hear, DJs talking about things that aren't relevant to them, or 8-12 minute long commercial breaks.
I think it's the latter. You could create a radio station with the finest contemporary rock, alternative or active, and nobody would listen because young people don't use radio anymore. Alternative and Active Rock stations play so much library material because they must catch over-40 listeners who still use the radio.
Radio was very important to people who grew up with it as their main source of music discovery and audio entertainment. That began to diminish with the growth of the internet in the 90s and 2000s. The people who grew up with radio being very important to them in their youth are now 40+ years old, so stations with formats centered on 30-year old songs are catering to the memories and emotional attachment of that audience.
That's likely to be a problem 10-15 years from now when those 40-year-olds are 55+, and there's no one coming up behind them who grew up with radio that way.
The radio industry should have been working hard over the past 30 years to make itself relevant to young listeners as an investment in its future, but there's very little incentive for corporate executives to do that. Short term results and instant rewards are always the overwhelming priority, and catering to an audience younger than the middle-age adult "target demo" is cravenly dismissed as a waste. In my view, the only real exception to that is iHeart building out its digital platform. While its usage lags behind Spotify and Amazon, at least they'll have a chance to retain some of those younger users in the long term.
