A philosophical question.

David Ten gave a most philosophical response. BTW, I like streaming services because it allows me to constantly try new artists and I like new.

I found the best recommendations on Spotify. Unfortunately, the sound quality is below par compared to Quobuz, Idagio and Tidal.
I never heard of Louise Farrenc, until Spotify.

My decades-long exploration of classical music has always been repertoire based.  By this I mean I always sought out those less-known or outright forgotten composers on obscure labels, rather than sticking to a core of canonical composers and pieces, and perhaps multiplying the number of recordings I have of one piece.  (Exception: Mahler.)  I explore laterally a period I enjoy.  For years I was after Mahler's near contemporaries, from Suk, Reger, to Martinu and a host of others.  More lately I got into the Stylus Phantasticus, and collected twenty recordings from the early Italians through Biber and beyond--mostly composers most people have never heard of.  For quite a while I was buying the installments of Hyperion's seemingly never-ending survey of 19C piano concertos.  Conclusion: you do stumble occasionally over minor gems, but you also listen to a lot of worthy but ultimately unexceptional music.  There is a reason the canon is the canon (or rather two canons: the canonical works by canonical composers).  But I suppose I have the completist gene, and the thrill of the hunt keeps me going.  It's not a question of guilt, but rather of curiosity and ultimately enjoyment. So many things are a chore, music shouldn't be one of them.

 Streaming has solved that dilemma for me. Not as much excitement as finding a new disc of great new music in the old days, but no sheepish “ what was I thinking” when it sits on the shelf forever after playing it once.

millercarbon, you are going to have to come over for dinner. We make osso buco/ lamb shank stew but sous vide the meat and add it and it's juice at the end. The stew is cooked with stew lamb and bones in the oven. Killer dish:)
My problem is I get bored with music I play too much so I am always moving around between genres and artists. If I don't like something I will revisit it weeks to months later because sometimes it is just my mood and I might like it the second time around. Having a large collection is nice. Much harder to get bored with it.
