The books I read, the movies I watch, the music I listen to...I really can't think of how any of it could be described as "disposable by design".
I read a book written in 1966 the other day. That's young by the standards of literature, and yet it's older than I am.
Netflix's entire business model is built on movies not having an expiration date.
And to call music "disposable" is a statement that I don't even know how to respond to.
