I’m aware that it has never been the intention of mAirlist to provide a scheduler which can compete with commercial software. At least that’s what I understood from the manual. Still it would be great if some additions to the scheduler could be made:
A great improvement would be the introduction of a NOT command, i.e. select a random song from folder X, NOT being from genre Y.
Maybe something for mAirlist 5?
Put a “!” character before the attribute value, this will negate the filter: “Genre=!Rock” => do not pick a Rock song.
Sorry I wasn’t aware of this feature, perfect! 
Neither was I, just stumbled upon it when reviewing the scheduler code for v5.0 
In addition to this, it would be really nice to have some more options in the Mini Scheduler:
[ul][li]Being able to use more Boolean Operators: Pick a song from folder x containing y AND z, or containing y NOT z.[/li]
[li]Being able to use more attributes at the same time: Pick a song from folder x “Genre=!Rock” AND “Genre=!Jazz”.[/li]
[li]Being able to use “.”: Pick a song from folder x with love in the title.[/li][/ul]
