I agree. In particular, I would add that many of these platforms serve the classical music listeners poorly, IME. I tend to see lots of a) overplayed pieces that I've heard a billion times like Vivaldi's Seasons and/or b) mediocre orchestras/artists (the Radio Orchestra of East Bulgaria or something). The ITunes catalogue is also rather weak, actually. Lots of great classical CDs can't be found there. Finally, in many cases I'm attached to a particular rendition or version. I don't want to hear the Brandenburg Concertos on modern instruments, for example, yet you'll often hear this sort of thing on these services.

So, at this point I have a very large classical collection that I've accumulated over the years that serves my idiosyncratic tastes. Until someone comes along that provides an equivalent experience -- and there's probably a market opportunity there -- nothing can replace it.
