Interesting concept! I'm nearing 30 myself and I find that I'm constantly looking for new music personally. In fact, I use things like Spotify to hopefully find me some good suggestions because I know there's lots of great music out there I haven't heard yet. Altho that may have been true for previous generations, I think that the way that we as a society now have access to music with all these online streaming services is going to change how we access and interact with music as we age. Who knows what'll happen in another 20 years.


Cheers,
Ember
