Well, yes. This exist — I am really grateful for that, but.. This audio library now contains 15M positions. It is a big number, no doubt about it.

Then, Spotify has over 80M files in the library with around 4M podcasts.

Estimated existing music amount is unclear but around 90-200M and growing all the time.

And suddenly 15M is getting somehow small in terms of preserving, and this is with music only.

With movies I even remember some interviews with Tarantino and Nolan talking about how badly some movies are being mistreated, lost cuts, not even close to proper/safe long time storing, fires, accidents and so on..
