However, the previous software lists it as 10.
In MusicBee, what figure do you see for the <rating> tag in the Tag Inspector? (which you can open from a right-click > edit) Is that the 200?
And also, when you display the <rating> tag in your main panel, what figure do you see there for such a track? (should be a digit between 0 and 5, I believe)
If you can establish a pattern between the actual rating from your previous player and the figures that MusicBee is showing in its <rating> field,
then you can easily filter your library accordingly and re-rate your files in batch (in other words, updating them to rating figures that MusicBee recognizes)
