again I guess nobody has large libraries. I have over 300k of mp3's and while most are tagged they are not in proper case for Album or Track Since you already identify these it should be simple to allow updating to occur when identified it could be an option within case rules dropdown. I am not complaining this and mp3Tag Pro are my friends. I already have renamer to make a '_' into a space and an empty directory delete.

apply case rules seems to be the largest issue I have artist 10cc, 10CC, 10 CC load to the Bluesound Vault 2 as 3 artists instead of 1 making it hard to ensure that all duplications are corrected same with missing Genre

This is a must and where most of the time saving is.

this would save a lot of time, with my collection i had to apply the rule manually and the suggested values have been used.... so far so good with bliss intelligence!

Anonymous, can you send me the example names that aren't working?

I woudl like to see this, especially on the "track" rules. However, ome considerations:
album or track tiles starting with "odd" letters / signs like "......live"

I didn't think this would take too long to appear :-D

I always tend to implement rules manually first to iron out any obvious bugs, then automate later. Thanks for posting this.
