I spent last winter ripping all my DVDs, and I did a lot of the organizing, changing file names etc. in the terminal. Because I could automate the process even a little.

When doing TV shows, I could take the names of episodes from an online database, put those in a text file, use block edit mode and macros in Vim to format them the way I want, then use a bash command to iterate over the lines in a file and rename them all. Hell I'd probably still be at it if I had to rename that many files manually, even using copy/paste.
