i like CDs because they're cheap (unlike vinyls), easily accessible (unlike cassettes), and you still get to hold a physical Thing in your hands(unlike streaming)!
i listen to my CDs on a magnavox mcr220bk.
i got it at goodwill for $8!
most of my cds are old (from the early to mid 2000s), partly because i like a lot of music from that time, but mostly because i get all of my cds second hand.
CD collection started ~september 2021
