Not sure if this will help, but I find the best program to work with music files is
Mp3tag.
It works with many music formats and allows you to look at, edit and organize tag info. I have a couple 100 gig on my drives. This program allows me organize the tags consistently. Bit rate is shown for every file. Much easier to use than windows file properties.
Also it is free. I have given Florian a few bucks over the years.
Facts don't lie or have an agenda. Facts are just facts
"God did it" is not an argument. It is an excuse for intellectual laziness.
