Aquinas turns 8 on Sunday, and I realized that I have exceedingly little music from the past 8 years in my collection - much less than the 8 years before that. Before I had kids, I had time for music. I would seek out new stuff, try different things, discover, etc. I just have so little of that now. It's a big part of why my tastes haven't continued to grow.
Now, maybe once a week, I just plug in my headphones and take a whirl around youtube for a night, clicking on whatever mostly familiar starting point I pick, and going from there. I jump around a lot, but not a ton of new things pop up. (A side note: it seems like all the algorithms (and this is true for Pandora, et. al., too) keep redirecting me to the things I know, not the things I don't know.) It's not really a time for checking out new stuff, because it's my rare chance to ground myself. It's a time of re-centering and recharging, not discovering.
So I don't know when to find time for more new stuff. After the kids leave home, I suppose. Maybe I'll be able to count on them to introduce me to music someday. I put a lot of effort into giving them broad exposure to the music I know, so maybe their tastes will be diverse too, and someday that'll pay off.
Anyway, what are your listening habits? When do you listen? Do you mix in old and new together? Do you find specific time for discovery of the new?
