I recently added my CDs to the B2. When this occurred to me I did a google search for the title followed by "CD". Many times it would appear on Discogs where I would find the track listing and missing cover art. I would do a cut and paste from the website, put it into a text editor (WordPad for me) and edit it to include the title text I wanted. I would download the artwork as well.
While you can't update anything while ripping, when the rip was over I would use the web page to edit the tracks. I would
- copy the entire line (one click to the left of the line),
- do a copy,
- go into the webpage and select the title by double clicking on it and then a paste.
If needed I would click on the album art which would allow me to select the file I downloaded and add it to the B2.
Definitely boring, redundant and makes for a tired hand.
