@bobjonkman True. And music is also pretty unique in how we reached high quality digital distribution since at least the CD and won't need higher, so you could probably estimate pretty well how much storage you'd ever realistically need for music.

Meanwhile for text, specially in the same timespan, there got improvements around encoding/formatting/… often leading to bigger data usage even when efficient, although I think compression improvements offsets that pretty well.
And Images or worse Videos do not seem to slow down at all in terms of requiring more and more data for what's considered "high quality", and for some reason software, even ones without anything multimedia seems to also grow similarly.
