I often find myself ripping CDs that don't have metadata on the web yet. Of course, I want to help out the community by adding this data, but sometimes I'm too lazy. To me, this sounds like a situation where the data entry should be made easier.
Sound Juicer has a menu item that says "Submit Track Names", but all this does is take me to the Music Brainz website, looking up the TOC for the CD. Then, the Music Brainz submission process is a little complicated.
