I find the discovery of new music through streaming to be the most amazing part of it.
This is a biggie for me. To be honest, I stopped listening to radio for the most part years ago, other than a couple of classic rock stations, which by their nature, never play any new music. I really didn't have a source of new music that I could check out until I started streaming. Now I'm always watching the New Releases on Qobuz and Tidal and hearing a lot of cool music. I often end up purchasing physical media after hearing something I like on a streaming service.
