college radio or free form is the answer to keeping it fresh and interesting. You can stream it or go terrestrial if you can pick it up. Either way it’s a fun way to hear new things and surprise yourself. Or hear some of your favorite tunes that would never, ever make it on commercial. (Of course some stuff that’s not my thing at all but I give it a listen.)
I’m a Gen Xr so it’s the way I learned about music beyond what was on the “radio” if you know what I mean. So in that sense it is a bit of nostalgia too. I just love it as a mix into my regular music playing program.
