"It would be nice to have color-coded highlighting on CD TOC pages, like this one. In this example, the length of track 1 is off by one second (there's another TOC there) but it's not easy to spot.

The table cells of non-matching track lengths (both in the TOC at the top and the album list at the bottom) should be marked with a red background to make them easier to spot.

I think both the TOC and the track length are stored in the database with better than second precision, so perhaps we should use a different color (pink? we already use yellow for edits-in-progress) for cases where the length match as represented (eg, 2:36) but don't match at full precision (eg, 2:36.00 vs. 2:36.55). A tooltip should explain the difference to the user. "
