I did just realize after posting maybe touting how affordable CDs have become is maybe not the best idea.
The people who really want to stop paying for streaming are going to turn to piracy, don't worry. Physical media will still be accessible for people who are willing to pay with space instead of money.
:'D
I can't remember the artist but there's a fun song about how they used to pick up second hand LPs really cheap and then they got popular and too expensive, then discovered second hand CDs are really cheap now.
Frank turner-ish vibes but I don't think it was actually him.
It's completely un-googlable though, and even the LLMs aren't much help on this one.
