Indeed. Bitcoin's blockchain grows with a laughable 3kB/s, yet is an unwieldy 700 GB.
A blockchain that allowed you store one song per second would be hundreds of TB before long. There are other architectures for that sort of thing for a reason.
Looks like BSV is about 7TB and grows at about 4GB a day. I have no clue what those guys are up to these days. This may be unweildy for a home PC but really is still pretty trivial for a data center.
500 hours of video is uploaded to YouTube per minute which is... If my napkin math is right, about a petabyte a day.
