You completely missed the point of what you are replying to. The point isn't that you SHOULD buy music from online sources instead of CDs. The point is that CDs aren't "the only way to buy a digital popular music in most countries." They are directly contradicting a point someone else made by saying CDs are not the only way to buy digital popular music in most countries. They even specifically said popular music, not whatever niche music some random person is into. They also mentioned iTunes because it services 119 markets, which directly counterpoints the statement about being available in most countries. They never advocated for iTunes like you imply.

It's almost like you lack reading comprehension. "Soms people here on Lemmy are even more insufferable than any other social media."

Many people don’t listen to local music or pop music.

I was responded to a comment about the availability of pop music.

And out of everything available iTunes is your first choice too?

Yes, the largest digital music store is, naturally, the first one I searched for availability numbers for (119 markets).

I don't really understand the rest of your rant.

I think you can use iTunes as a catch all for sales of digital files, including bandcamp. As opposed to a physical disc or a subscription. FWIW I was just looking this up on the RIAA website and you can run reports by year or year over year comparing media options. It’s really interesting to see which year each format peaked. Eg 8track 1978, cassette 1989, CD 2000, digital file 2012. It doesn’t include limewire /napster (non-revenue) so the unit counts are a bit depressed. I wish it included pre-iPod mp3 players and blank CD sales.
