Song Tag for Hoster Database
 

I think what's needed here is a tag system for song files right click over file and get Disc ID info (Not BookID) Example SC123-04 or CB4567-10 and have an option to rate the file with a star or asterisk or color ( Red = Very Good or Explicit Content ).
You have control of your music. You buy it, you imported it, you print the books that list it do a good job you work do a bad job you Don't simple.
I think this brings you closer to managing your song database the way you see fit as a host.
This feature will enable you to see instantly your song database from a rating standpoint. and it doesn't mean if a regular wants the One star version you don't play it.
I keep my good songs on Drv C: and the others in my external Drv. so if I have it you get it no matter how it's rated (Venue permitting).
