To add on. What is not accounted for is TIME.

For example Dark Side If The Moon was made during a 6 month lock out for the whole of Abbey Road Studio 2. Lock out means the studio is available at all hours in that time. Essentially the band own that space.

Say those facilities now exist in a laptop (they don’t really). Then it still takes the musician TIME.

Ironically a big tune on that album was also labelled time.

For streaming revenue, the average musician should be submitting short test tones until the situation improves.
