The services Tidal and Qobuz give user-controlled access to most music in album form, often at higher than CD resolutions. I listen via Audirvana Studio, a Schiit Jotunheim DAC and balanced headphone amp, and Aeon 2 headphones.

My interest has reawakened in deliberate listening to music as organized by the artist.

I once sat next to a friend of Steve Jobs, on a flight. He appreciated my admiration, and took a drawing of a "current mirror" iPod charging circuit to show Steve. The conversation became uncomfortable when I asked if Jobs wanted his legacy to be the death of the album.

Jazz is the higher mathematics of music. With Tidal or Qobuz, it's easier than ever to begin an exploration of this world.
