This is approximately the sort of application that I intended Data::Sync to be useful for artist, you could use DBD::CSV & DBD::MySQL handles with it. OTOH, if it doesn't do what you need, I'd love to know why so I can address the shortcomings.

Update: v0.04 includes attribute/record hashing, so a record is only written to the target if it has changed in the source, something your OP suggests you might need. I've got some other functionality to include in it, so I haven't uploaded it to CPAN yet, but if you want to try it out, please /msg me.
