any chance of a new weighted random condition, relating to the age of the music.

E.g I want to make the songs in my library from 2010 more likely to play than those from the 1970's

any suggestions as to how I can currently do this, would be greatly appreciated

thanks

It's not possible currently, I'll add it, don't know when. Probably with the possibility of choosing the "preferred" year.

The only way you can get this result currently is by giving songs labels corresponding to their year (or decade) and set a probability for each of these labels.
