Replace old song upload?

Is there a way to have old versions of songs removed when uploading?
I have a bunch of low bit rate songs I want to replace with 320/flacs.

You can’t. And I don’t think there’d be a good way to add an option for something like that. New files won’t match the hash, so checking that won’t work. It doesn’t make sense to add it to the sync command as it would defeat the purpose of the command.

I’ve had in the back of my head to add a dedup command to remove duplicates in definable ways, but I don’t know when I’ll really get to doing that properly. For now, you could use the delete command using the -f, --filter option to target the songs you want based on bitrate and other metadata.
