I’ve thought about doing this and the ease of music discovery is the primary reason I stick with Spotify.
The author says that with a decade of refining their music pallet they know what they want is nauseating. I’ve been at it for 2 whole decades (twice as many!!) and discover new music all the time. Sure I’ll jam to what I have here and there but then it is always back to searching.
I live the idea but it isn’t practical. I’d spend more money buying music than renting.
My wife on the other hand might be okay with 10 albums and a steady drip of lofi.
