Because I think the issue is similar in that it involves multiple columns and ratings, I wanted to be sure this was listed here in this thread, b/c it would make sense to fix all of this at once:

Thx.
EDIT:
I also want to add that all apps I know of, now write the same exact 5 POPM values for the 5 whole stars, which makes ratings handling easier, namely 1, 64, 128, 196, and 255. I got MM to conform to windows explorer's de facto standard. Not sure tho about reading ranges, half stars, etc.
