Mine haven’t been so much as re-discoveries as discoveries. Recently discovered some great west coast hippie stuff from the late 60s to the early 70s. It also opened my eyes (well ears actually) to Jimi Hendrix someone who ashamedly I somehow overlooked. Now I’m going through a list of recommendations from HiFi+ on Americana and discovering bands/artists I’d never heard of that I should have.
None of this would have been possible (or at least as easy) without streaming.
