Describe the solution you'd like

by using other tools, some error dectection can be automatic.
If QobuzDownloaderX-MOD can execute any exe/script(bat/shell) after download, I can use command
flac -t song.flac 2>error.log
to detect if there is download error.
And more possibility, such as by using up.sh, we can just encrpy and zip all songs and upload to filehost service automatic~
