Good advice from SRS. My only concern would be in regard to the way the cd booklets will be printed. If they will be printed at high resolution at a commercial printer then legibillity will be less of an issue. If you will be desktopping these yourself then I might nix the dark background. The rule of thumb is newsprint is generally 10 point in size. You won't have the luxury of 10 point font size on your cd booklet though, probably more like 8 point. I would go for an attractive serif font (Times, Palatino) for the body copy and a complimentary sans serif (Futura, Univers) for your headings (song titles etc). Leave enough space between titles for eye rest. Good luck.
