Vey cool, Chris! I have probably 2500+ albums on disc in ALAC and it is only slightly over 1TB, so 30TB is just a staggering thought!
Every name you named I have, and really enjoy. I love early San Francisco rock. Santana will always be my favorite; he is my inspiration for the guitar. I play QSMS (I love you said QSMS instead of the later QS!) Happy Trails all the time. Grace Slick's anger fueled me during the late 60s. But, then, I like Zeppelin, HP, so many English bands, not to mention prog rock. I have been on a Kansas kick again of late. And, I have got a lot of blues guitar albums. Ronnie Baker Brooks is on the playlist today. So is Jeff Beck Live +. That album kicks arse with Rhonda Smith on bass and Jimmy Hall (Wet Willie) singing. PF and Gilmour go without saying in our house. Half the stack of DVDs next to the machine must be one or the other Gilmour.
And, with tinnitus that is enough to drive me nuts, I play ambient stuff in the background all day long to cover the screaming in my ears. Did you know one can have multi-tone tinnitus? It's been pretty crazy. Thank you, Pfizer vaccine.
BTW, I suck at guitar, but I have played nearly every day for a lot of years. Mostly blues, so I can play my song, not theirs. I love jam tracks for backing. The arthritis has left me unable to play chords, but two note partials can pass usually. You don't have to be good to entertain yourself at home, you just need a tolerant spouse. Guitar and keys are what kept me as sane as I get during the 15 years I have been stuck sitting in a chair all day. Things are a bit better now and I can do some shop again, but it is still my joy.
