Auto-generation of the file and file names would definitely help. I'm sure there are a lot of people that already have mp3's tagged that would just be extracting the lyrics and submitting them. If there are fields missing you can just have it do as I said above.

PS - Sorry about the ftp site being messed up for a few hours, if anyone noticed. I forgot to put something in the config file when I added the last few users. All fixed now though.
