As of 2022, CDs accounted for less than 3% of music sales.
As of 2023, in England, CDs and vinyl accounted for 9.4% of music sales and year to year growth for CDs is at 5.4% ($127 million).
In the EU, CDs account for over 10% of all sales with growth at 7.3% year over year.
In the US, CD are a bit less than 3% with sales (but account for over 10% of revenues) and hover around 37 million per year since 2023 and 25% of consumers say they use CDs for listening. There's as many ways to skew stats as there are to skin cats.
The tremendous number of streaming sales is mostly from youngsters and Gen Zers downloading pop music and are not audiophiles. People have to stop using that red herring to validate their position. They listen on cheap, branded IEMs and headphones that no self respecting audiophile would use, or just blast it out of their smart phones (as anyone who spends even a few moments in public can attest to).
And yes, there are millions of pieces of music out there with streaming that no one is listening to. Availability does not equate to acceptability (clumsy, but I was going for something catchy). It's like saying one library is bigger than another to someone who could care less what's in the cooking and home improvement section.
All the best,
