First of all a huge thanks to Steven Mayall and anyone else who has helped making MusicBee such an amazing programme!
I have some 5,900 music files falling into 40 genres, of which 6 have sub-genres. You may wonder why I have sub-genres, but there's a heck of a difference between the various styles of blues, classical, jazz and so forth. For instance, within classical sometimes I like to listen to piano works and, at others, only symphonies.
My definition of genres reflect on my desire to listen to music (i.e. it prevents me from listening to a mixture of Chicago Blues and Classical Overtures).
Hence my suggestion that it would be wonderful if MB would allow filters to be defined and stored so that I quickly can select from my library music according to my mood - be it Classical, Soul, Jazz, whatever...
An implementation of that would be to have, under "Auto DJ Settings" -> "Apply Filter", user defined and labelled filters (e.g. Blues; Jazz; Latin; Folk; Soul). Such defined filters may also be made available in a very handy way through a right-click on the "Auto DJ" icon to the left of the "Now Playing" title of that column (presently a right-click there will allow one to "Configure Layout").
Again, many thanks for all the efforts
