Buy Or Stream

when I buy music albums I’m buying the ability to listen to it as many times as I want forever without paying something for it. Has anyone figured out the cost of buying your music library entirely vs streaming subscriptions for, like, 20 years? 20 years at $10/month is $2,400. If you just bought albums you listened to all the way through and filled in other songs/artists you liked as singles I’d say the cost would be close. Especially you can find most stuff on Youtube if you are willing to suffer through an add.
