I can stream more than 20cds worth from a catalog far more expansive than anything I could dream to store. It’s simply worth the money for my usage. Moreover, I don’t want to store anything locally, physically or otherwise. I’m ok with the risk of them pulling licensing, because after over a decade and a half of usage it’s been an issue thats come up fewer than 5 times, and each time there was an alternative track/release available (i.e. part of a newer album or rerecorded).
