Hi, thanks for your input. There is nothing wrong with my music files; like I said all of my music files are Not read-only files. It is definitely a MusicBee problem since when I try to do the Search & Replace, (I've been trying all day) like I said it just does the windows ding and does not allow me to click on anything, nor type anything in any box, no box appears, until I hit Esc to get out of it.
Separate problem: the plugin "Additional Tagging & Reporting Tool", I don't know where to find the functions for it either inside of MusicBee, and yes, I've copied the files into the appropriate MusicBee x86 folder. I'm close to giving up and just going into each individual file for about 200 songs and deleting the dj's stamp tag in multiple fields myself... *sigh*
