My dad is exactly the same, he's 67. Still has his vinyls - about 300 - and a lot of his cassettes. He loves the CDs though.Old people love CDs. My old man has gone records, cassettes, CDs in his lifetime and never had any difficulty with the change of format.
Digital media is different though, there's nothing physical you can touch. I don't think people older than 60 trust it.
Thought about introducing him to Spotify but I reckon he'd struggle to grasp it.
