I feel for the people who prefer sleeping in the buff.

However, these existing efforts have some major issues:

Over-focus on the most popular artists. There is a long tail of music which only gets preserved when a single person cares enough to share it. And such files are often poorly seeded.

Later…

We primarily used Spotify’s “popularity” metric to prioritize tracks. View the top 10,000 most popular songs in this HTML file (13.8MB gzipped).

I must be kinda stupid, but it sounds to me like there’s some double speak. “Only popular music gets preserved, so we preserved music by popularity”
