What if I heard from a friend that "Bach" is his favorite composer? I shudder to think what you'd get if you just went on Amazon and typed "Bach".
Here's what happens when I type "Bach" into Spotify:
"Top result": Johann Sebastian Bach
"Songs": the 4 tracks listed are all from "Harnoncourt conducts Bach".
"Featuing Johann Sebastian Bach": Four Spotify-curated playlists: "This is Bach", "Johann Sebastian Bach radio", "Chilled Instrumental", "Bach Concertos".
"Artists": the first two listed are JS and CPE.
"Albums": The 5 that appear first are the violin concertos from the Freiburg Baroque Orchestra, the cello suites from Yo-Yo Ma, two-piano concertos from Lucas and Arthur Jussen, the Goldbergs from Lang Lang, and the solo violin works from Augustin Hadelich.
Let's click on the playlist "This is Bach". The description is "He perfected counterpoint, set the bar for cello suites, and absolutely loved a curly white wig: JS Bach played a huge part in shaping all the classical music we enjoy today. Discover why, right here." The playlist is 70 tracks (looks kind of like a random selection), about five and a half hours worth of music, from well-known artists.
All anyone needs to do is click "play". I don't buy this "oh, it's so complicated" thing. If people truly like the music they'll put in the little bit of effort needed to get a handle on it.
Now someone with a popular-music mindset of there being a canon of recordings comes in and there are 5000 Mozart collections and no clue which ones are "the good stuff".
But they're not going to care. The notion that you should get
this performance and not
these other hundred performances is a barrier that most potential listeners aren't even aware of. They won't know that they should listen to "Glenn Gould, Roselyn Tureck and Edwin Fischer" (to quote the first result when I Googled "great Bach pianists"), they're going to see Lang Lang's Goldbergs and think "I think I've heard of him", or see Vikingur Olafsson's album and listen to that because it's got a cool-looking cover.
