Thanks Bex
That was partially effective. About 6 tracks (in about 3500) still insist in getting their own Track # even when the library is rescanned

To get rid of this behavior, deselect "Infer track properties" in Tool->Options->Library.

I normally keep the Track # field blanc and while I was removing some track number entries I noticed that, if the track has
a number in the name in the name ie 500 Miles or 1812 Overture or a number in the artist name ie B 52s or 1927 then
the Track # grabs 50, 1812, 52, 1927 in the examples previously mentioned.
Interesting I thought.
