Alot of the time, you can just email their booking email asking to buy their album with cashapp et al and they'll gladly take your money and ship you a zip file of MP3's, assuming the band/artist is small enough.
And you could replace Dropbox quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software.
funny thing: i recently happened into the solution to that age-old question of "how do i transfer some file(s) between two computers in the same room". i now run an anonymous FTP server on my laptop, open to the LAN. prior to this Dropbox _was_ one of the solutions, but recently i've used that FTP server for the job several times with both Linux and Windows users.
In a directory as a lazy way to transfer a file (especially to my phone).
It is not encrypted, and I wouldn’t be that surprised if it was also vulnerable in some ways, but it sure is easy (and it is only for lan, and pretty brief).
Magic Wormhole is great, but sometimes unbearably slow for bulk transfers. (I imagine the public relay server used for the common NAT-to-NAT case is sometimes overloaded.)
